Thirty years ago, Luke Creswell and Steve MacNicholas converted the Dustbin Song they performed with their Brighton-based street-skiffle band Pookiesnackenburger into a bigger act, and Stomp was born. The bin-clattering, broom-banging dance act that emerged has since become an international hit, and this summer it’s back for a long run of shows at the venue where it was first performed, The Old Market, in Hove.
