Fanfare (1958) Directed by Bert Haanstra. Dutch Comedy
After a fight the brass band in a small village splits up into two separate bands.
They both want to win a contest and will do anything to prevent the other band from winning it.
What makes this movie really funny is the fact that the man with the triangle (the tiniest instrument of the all) plays the crucial part.
He is the one what it's all about, even while you can't hear him at all.

This band is playing a warm up for the Melbourne Jazz Festival 2011
