Here's a bit of fun, might tickle you.
EXT. STAGE 5 AT GLASTONBURY - DAY
There's no band on stage, as TV presenter Johnny Fab runs on stage.
JOHNNY (into hand mic)
Helloo!
CROWD
Hellooo!
JOHNNY
Well, I hope you enjoyed Status Quo before the break. We've got some more great music for you now. They've been finding it hard to get gigs, and local councils are banning them, but we've got them here for you now. Here they areā¦ THE ICE CREAM VANS!
Three ice cream vans drive onto the stage and in perfect unison being playing playing Greensleeves over their speakers.
