Limber up Londoners: the organisers of a flash mob are looking for volunteers who are willing to bust a few moves en masse around central London on September 20. But this won’t be your average flashing and dashing. Inspired by the MP3 Experiment in New York, The London Undersound involves getting participants to simultaneously listen to a podcast that will deliver all sorts of random instructions, from throwing down your fanciest freeze to playing follow the leader. It's a celebration of good times and silliness that comes from the folks behind Freeze Waterloo and the annual No Trousers on the Tube event, so if you can imagine the joy of unleashing your post-summer pins on rush-hour commuters later this month, this should be just as liberating.
Have a look at how the New Yorkers got down:
