But now back to earth, back to Berlin, where 27-year-old Elisa Klein is a dancer at the city's famous variety-and-cabaret-theatre - "Friedrichstadtpalast". It's the largest of its kind in Europe, with well over 60 dancers from all over the world. Well, the chorus-line-girls might make it look all easy on the night, but it's a really tough job. Elisa took us behind the scenes to see what it's like - being a dancing celebrity, on one of Berlin's most glamorous stages.
