The mostly young music fans have crowded around the Victory Column in Berlin's central Tiergarten park on Saturday afternoon to watch internationally known acts such as a-ha, Crosby Stills & Nash, Roxy Music and Green Day as well as German favorites including Wir sind Helden, Silbermond and Herbert Grönemeyer.

German favorites Die Toten Hosen kicked off the concert, electrifying the crowd while reminding the audience that helping Africa was the most important part of the event.

"This isn't a rock concert. It's a demonstration," Campino, the singer from the group, yelled to a jubilant crowd.

Germans and visitors from around the world packed into the wide boulevard that runs through the downtown park waving banners with the German band's logo as well as British and Argentinian flags.

They and other performers, who each had just about 10 or 15 minutes of stage time, were part of a global concert series on Saturday which took in 10 cities and four continents. The free concerts began with Tokyo's show (photo) and with end in venues in North America. Besides Berlin and Tokyo, the concerts are taking place in London, Paris, Rome, Cornwall in England, Philadelphia, Barrie in Canada, Johannesburg and Moscow.

The shows were the brainchild of British musician amd former frontman of the Boomtown Rats, Bob Geldof, who wants to build a critical mass that will pressure leaders of the Group of Eight major industrialised nations meeting in Scotland next week to do more to alleviate poverty, particularly in Africa. Goals of the campaign include doubling the amount of aid which goes to Africa, relieving the debt of the world's poorest countries and putting fair trade policies into place to help developing economies.

This series comes 20 years after Geldof's first anti-poverty concert event, Live Aid. But unlike 1985, when an estimated 1.5 billion television viewers tuned in to watch Live Aid and donated over $100 million (83 million euros) for Ethiopia's famine victims, organisers hope to use modern technology like the Internet and mobile phones to reach an even bigger audience.

On Saturday before the show in Berlin, German celebrities such as Grönemeyer and supermodel Claudia Schiffer showed their support for the campaign to fight global poverty. At the Brandenburg Gate, they signed a banner carrying the slogan "Your Voice Against Poverty."

Criticism in Berlin

However, the show in Berlin came in for blistering criticism from event managers, who lambasted the German parliament and the city for not giving sufficient backing. In a newspaper interview, Marek Lieberberg, a veteran event manager who is putting on the show in Berlin, accused Berlin Mayor Klaus Wowereit, German authorities and businesses of "stinginess, ignorance and Wilhelminian absurd bureaucracy"

He complained that German companies did not come forward to sponsor the event as firms had in the other cities where concerts are being held.

He also criticized lawmakers for not allowing the concert to be held on the plaza next to the Reichstag, or parliament building.

But on Saturday, music lovers seemed little concerned about organizational glitches. Many in the audience carried red balloons or t-shirts that read "Make Poverty History." Families were strongly represented and children were often hoisted on fathers' shoulders so they could at least catch a glimpse of the stage.

Many of the 150,000 spectators had to watch the bands on giant video screens that had been set up since the location's space limitations meant that only some 40,000 had a direct view of the stage.
