Musicians light bulb joke

Question: Do you know how many musicians it takes to change a light bulb?
Answer: No, big daddy, but hum a few bars and I'll fake it.
Answer: Twenty. One to hold the bulb, two to turn the ladder, and seventeen in on the guest list.
Answer: Five. One to screw in the light bulb and four to stand around and say, "Man, if I'd had his studio time, I could have done that."
Answer: 5, one to change the bulb and 4 to get in free because they know the guy who owns the socket.
