Years ago, in a venue called "The Spot" in Evanston, IL (a place which has, alas, gone the way of all things)ayoung man (whose name escapes me at the moment. If i remember it later I'll post it) stood on the stage telling a long, meandering story (to inroduce what turned out to be a very short song). The longer the storyu wnt on , the more bored and annoyed the audience became. Finally, some body stood up in the back and yelled, "SING SONGS!!!" The young man leaned into the microphone, looked the heckler directly in the eye and yelled, "DRINK BEER!!!"
it's one of the best saves I have ever seen.
