And if that didn't whet your appetite, here are a few classic jokes about musicians and singers.
Q - How many Sopranos does it take to screw in a lightbulb?
A - One, but all she has to do is stand on a chair, hold the bulb and expects the world to revolve around her!
Q - How many Altos does it take to screw in a lightbulb?
A - Two, one to screw it in and the other to say "Isn't that a little high for you?"
Q - How many Tenors does it take to change a lightbulb?
A - Four, one to change it while the other three moan that they could have got that high too!
Q - How many Basses does it take to change a lightbulb?

And finally just in case you thought the Conductor had got away with it:
Q - How long does it take for the conductor to change a lightbulb?
