People of all ages and all levels of experience came to The Place on Sat 8 May to learn a few simple dance routines which were filmed to be broadcast during the Eurovision Song Contest on Saturday 29 May.
There are flash mobs happening in Oslo, Düsseldorf, Ljubljana, Barcelona and Reykjavik, and more cities are being announced each week as the momentum gathers.
Peter Svaar, Head of Press for the 2010 Eurovision Song Contest on behalf of host broadcaster NRK, said: "We want to share the Eurovision Song Contest, rather than just broadcast it. With 18,000 people live on location in Oslo dancing, plus video footage of large flash mob groups from ten major cities, the song, the movements, the arena, and all the cities will share a common musical experience together."
