Just dance.

Yeovil had a 'streetfest' weekend this wekend, several dance acts came and did their thing, there was a mini fairground, a bouncy castle and various other things designed to wring as much cash out of stressed parents amuse the children. The acts did their thing then they retreated to the bigger stage and the audience could go on the dance floor and they would be taught the moves.
Apparently this group were from a television show on Sky, I wasn't all that impressed at that but judging by the screams coming from the young girls clinging to the stage I'm guessing they were pretty popular!
