I have a feeling Mick was exaggerating a little bit on the blood side of things but I'm sure the throwing the guitar against the wall and watching the show from the board deal is true though I've heard conflicting stories about whether he heckled them during the performance, critiqued then after the show or said "it was a good show" to them afterwards but whatever, Danny's music was and is great so that's all that matters to me personally anyways.
