Recently the Eurovision Song Contest announced that the interval act on the night will be footage of one giant flash mob taking place all over Europe.
Flash mob fever is invading Europe country by country, and its coming to London on Sat 8 May 2010.
Its a big responsibility ... how big can we make it London?
We are looking for people of all ages and all levels of experience to learn a few simple dance routines which will be filmed for broadcast during the Eurovision Song Contest on Saturday 29 May. Eurovision is watched on average by 125 million people each year, and they could be watching you!

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."
