Prom 24 - BBC Radio 3 - World Routes Academy

I have never seen so many empty seats in the Royal Albert Hall. Empty, because it took all of three minutes for the audience to descend en masse to the standing arena, transforming it into a dance floor. Children and grandmothers alike got up, unable to resist the heady pull of the music. When the dance floor was full, the audience simply danced in the stalls.
