Number one choice would undoubtedly be the Sex Pistols at Randy's Rodeo in San Antonio, Texas, where the crowd was seemingly out for blood, and Malcolm seeming all too eager to provide it. Sid drops his bass on some idiots head, God knows what all got thrown about that night, I've always loved this pic of Paul onstage after the show....
Drink? Don't mind if I do
Randy's Rodeo
Second would be some Joy Division gig, never had a chance to see them.
Talking Heads Stop Making Sense tour was better live than the movie, which is pretty damn good.
Madness would be on the list as well, they played a heavy metal bar on their only jaunt through Oregon (79 or 80).
Any Fall gig around the time of Hex and Perverted By Language.
