Two notablyt bad bands I've seen were both replacement warm-up bands.
Late 1976, Pittsburgh Pa (Civic Arena). Doobie Brothers with Boston. This was right as Boston was exploding on the scene. We were pretty pumped, but it was not to be. From the stage (not in advance) they announced that Boston's equipment truck had broken down, and they weren't going to play. The replacement was something like "Split Lips". Never heard of them before or since. The main thing I remember is the guitar repeatedly apologizing because he had a brand new guitar and he wasn't used to it. To be fair, I imagine playing infront of ~15,000 people on short notice could be a little stressful.... But rule #1 ought to be to avoid making excuses for why you stink.
Another was Patti Smith Group. Also in Pittsburgh, July 1978. New Leona Theater. The warm-up band was supposed to be David Johansen Group. I don't remember what the excuse was, but they didn't play. The replacement was a local bar band, "Iron City Houserockers". My main recollection is large portions of the crowd turning their backs and giving double fisted "single-finger" salutes. [aside: some internet research shows that was the last show at the venue]
