They keep on rolling: The Stones are still touring across Europe, 60 years after the band played their first-ever gig, at London's Marquee Club on July 12, 1962. A new four-part BBC documentary series, "My Life as a Rolling Stone," focuses on the four core members, Mick Jagger, Keith Richards, Ronnie Wood and the late Charlie Watts. Here's a look at how they became so legendary.

Mick Jagger and Keith Richards met each other at school. In 1962, they founded The Rolling Stones. Also performing at their first concert in London were Tony Chapman (drums), Dick Taylor (bass) and Ian Stewart (piano). Another line-up followed with Brian Jones (second guitar), Bill Wyman (bass) and Charlie Watts (drums), who performed on the first album, The Rolling Stones, in 1964.

With their feel-good pop, The Beatles were already achieving world fame in 1964. That's why Andrew Loog Oldham, then manager of the Stones, wanted to create a group to counter the Fab Four. They were to become famous as the "bad boys" — though during their first TV performance in the show "Ready Steady Go," they came across as harmless good guys.

One year later, on September 11, 1965, the Stones gave their first concert in West Germany — in the somewhat conservative city of Münster. The police had a hard time keeping their fans under control. Most residents in Münster, however, eyed the Stones with suspicion. In fact they were lucky. Fans in Berlin demolished a stage during a later concert, which would take seven years to rebuild.

During the late 1960s, no other band came to embody the image of the hedonistic rock band more than the Stones. Groupies and heavy drug use were par for the course. Hard drugs eventually took their toll on Stones guitarist Brian Jones. He left the band in June 1969 and a short time later, drowned in his swimming pool under mysterious circumstances.

In May 1965, the Stones went on their third tour across the US, playing cover versions of rock hits once more. They still hadn't produced enough songs of their own. One night, Keith played a new melody on his guitar, and loved it so much that he recorded it and had Mick listen to it. It was the hookline of their first worldwide hit, "Satisfaction."

The Altamont Free Concert, initiated by the Stones management, was intended as a peaceful counter event to Woodstock. Alongside the Stones on stage were, among others, Santana, Crosby, Stills, Nash & Young, and Jefferson Airplane. When the Stones appeared, the crowd got out of control and the concert had to be interrupted. Hells Angels were behind the commotion.

When the Stones started playing "Under my Thumb," a man collapsed in front of the stage after a member of the Hells Angels stabbed him in the back. The band was deeply shocked. "If Woodstock was the dream," said British photographer Eamon McCabe later, "then Altamont was the nightmare." This day, December 6, 1969 is said to mark the end of the hippie era.

The band faced tax troubles in the 70s, which led them to flee to France, where they recorded "Exile On Main St." in 1972, considered by many to be the best Stones album ever. In 1974, guitarist Mick Taylor left and was replaced by Ron Wood.

Drug busts complicated the band's international tour plans. Charged with "possession of heroin for the purpose of trafficking," Keith Richards was sent to rehab to avoid a long prison sentence, while Mick Jagger continued his jet-set lifestyle. Musically, they experimented with different musical genres, dabbling in funk ("Miss You" in 1978) and disco ("Emotional Rescue" in 1980).

Overcoming those problems, by the 1980s the band was back to doing what they do best: performing live concerts. They were in such demand that they easily filled entire football stadiums — including in Germany in 1982, where they played many legendary shows.

Even after founding member Bill Wyman left in 1993, the Rolling Stones simply carried on into the next millennium, playing stages around the world. The idea of a farewell tour popped up a few times, but they kept on rocking. Despite their age, they never failed to put on spectacular shows. This photo was taken in 2003 in Moscow.

In 2006, Japanese fans enjoyed a Stones concert in the city of Saitama, north of Tokyo (pictured). Some time later, the Stones performed in the Serbian capital of Belgrade. True fans know where the band's name came from: Apparently, Brian Jones was inspired by the blues hit "Mannish Boy" by Muddy Waters, which contained the line, "I'm a rolling stone."

He was the Stones' backbone. But in 2004 drummer Charlie Watts was diagnosed with cancer. Radiation therapy led to recovery, and he continued touring with the Stones for many years. His last concert was in August 2019, as part of the "No Filter" tour. Two years later, he died at the age of 80.

At 65, he is way younger than all other members: Steve Jordan was first hired to fill in for a few gigs and finish the Stones' "No Filter" tour in the US after Charlie Watts' death. Now he has joined the world's longest-serving rock band on their European tour.

Following the death of Rolling Stones drummer Charlie Watts on Tuesday, the remaining members of the band posted different tributes on social media. Mick Jagger posted on Twitter and Instagram a photo of his bandmate smiling at the drums, but poignantly didn't add a caption revealing his feelings. Keith Richards also posted without comment a picture of a set of drums with a "closed" sign on them.

Elton John also reacted to the news of Charlie Watts' death by posting a picture of them together in the early 1970s. "A very sad day," he wrote on Instagram. "Charlie Watts was the ultimate drummer. The most stylish of men, and such brilliant company."

Even though the idea that the Beatles and the Rolling Stones were rivals is widespread, that is all a thing of the past. The former Beatles singer-songwriter was one of the first to post a video of condolences on social media. "He was a lovely guy. ... Charlie was a rock. A fantastic drummer, steady as a rock. Love you, Charlie, will always love you," McCartney said.

"#God bless Charlie Watts we're going to miss you man peace and love to the family," tweeted the former Beatles drummer, who also posted a few shared moments with the fellow musician. In one recent picture, they are portrayed smiling as they hold onto the same drumsticks. Another shot from the 1970s shows them in deep discussion at a party.

Reacting to Watts' death, the Who singer Pete Townshend recalled in an Instagram post that "Charlie Watts wept at Keith Moon's funeral" — the Who's former drummer, who died in 1978 — "I wish I was capable of such tears today. Instead I just want to say goodbye. Not a rock drummer, a jazz drummer really, and that's why the Stones swung like the Basie band!! Such a lovely man."

The Beach Boys' lead singer tweeted: "I feel terrible for Charlie's family. Charlie was a great drummer and I loved the Stones music, they made great records. Love & Mercy." While the Rolling Stones were recording "My Obsession" for the 1967 album "Between the Buttons," Wilson was invited down to their studio; it remains one of his favorite Stones songs.

On her Instagram account, "This is Patti Smith," the celebrated singer-songwriter and poet begins each caption with the words, "This is." She paid tribute to the Rolling Stones drummer by posting: "This is Charlie Watts. Mourned and beloved by all." As one fan commented, her words reflect Watts' style: "Short, sweet and deep."

Sheryl Crow is a huge fan of the Rolling Stones, and she has appeared on stage with them many times. Following the news of Watt's death, she expressed her grief on Twitter: "A hero is gone. No words. A huge gaping hole in the universe."

The Stones also had a notable influence on Lenny Kravitz as a teenager. When he later became a rock star too, he had different collaborations with the legendary band. As he wrote on Twitter, listening to Watts' music remains the best tribute: "The beat of The Stones. There are no words, every groove has spoken for itself."
