Listening to my archives, I came across the following exchange. At the end of a Grateful Dead concert (1970-09-19, Fillmore East), as the crowd keeps shouting for an encore, Phil Lesh and Ron “Pigpen” McKernan come out.
[Crowd cheer]
Phil: Hey, ah, what we want to say is, thanks very much. But it’s been a really long night and Garcia’s got a cramp in his hand and we’re all tired and Bobby’s lost his voice! So… good night..
[Crowd gets louder, disgruntled]
Pigpen: Wait a minute, wait a minute. Why don’t you guys go home and FUCK SOMEBODY?
