You Don't Know What You're Doin'!(1931)

Crowds throng into a theatre where a jazz orchestra are pumping out some lively toe-tappers. "Piggy" wants to take his girlfriend along to the concert so after an entertaining journey from her home on his dodgy looking contraption, they arrive and a bit of Al Jolson humour sets up a brief opportunity for an animated showcase of the sounds of Gus Arnheim's orchestra. That's all until she declares that they don't know what they're doing - and grabs a saxophone to engage in a bit of a duel with the trombonist before the pair steal the stage altogether then flee into a musically themed town. It's all too bitty for me, the scenes don't really work together to build any kind of story. It just seemed more of an excuse for the jazz lovers to grab a few minutes of airtime. Nothing special here, sorry.
