A patron at a hick bar Jim and I once played at (with The Pillar of Flame on drums - pre randissimo) demanded that we "play a song with words!"
Another time we were playing a Christmas party in a restaurant, sans drummer, and a woman (probably a glass or two past her limit) came up and said, "when are you going to play some real music?" "You know (shakes her hips)--dancin' music!"
When are you going to play some real music... I can't think of a more inappropriate question to ask a musician!
