A friend of mine was in a very modest band and when someone would inevitably shout “Freebird”, he’d extend his middle finger and should back “No charge!”.
“shout back”
Sheesh.
A band friend of mine extends his middle finger and says, "This one's free, but the next one's going to cost you!"
By the way, I play in an acoustic duo. We usually play "Locomotive Breath" acoustically, but aggressively, at our gigs. It is surprisingly well received, even by people who are unfamiliar with the original.
