Among blues musicians the hell songs are "Mustang Sally" and "Sweet Home Chicago", and in parts of the country there's always some clown yelling "Play Freebird".

A friend of mine who had a blues band in North Texas used to stop the band, and yell over the microphone "We don' Know any Lynryd Skynyrd, but just for you we're gonna practice them all week and THEN NOT DO 'EM, just for you."

A leading blues musician around where I live in N. Calif. burbles over the microphone "I've had to do this song for twenty years but bartenders love it so buy lots of booze and get sh___faced, here's Mustang Sally."
