I think Lemmy developed an intolerance to pretentious fuckery on stage due to the time he played with Hawkwind. When they played live they used to have a 6'4 nude lady sauntering around and doing "interpretive dances", a guy with a typewriter in a guitar strap over his shoulder, writing poems and offering them to the audience, and other stuff like that.If I remember correctly there was a clip of Limmy Kilmister where he criticized Rage Against The Machine for not playing for the audience like they were supposed to. He also said he would have thrown rocks at Rage Against The Machine.
I love how he leaves at the "And I want to go home now" part of Round and Round lmao
