Duds - T-Rex: couldn’t play live if their lives depended on it (who is that stupid little git struggling with the mike trying to sing?).
The Ramones circa ‘89 going through the motions with about as much enthusiasm as a nun at a rave (although our over-zealous local narcotics law enforcement agency may have had a hand in the outcome].
Chuck Berry circa ‘85 - well his ding a ling wasn’t on fire, that’s for sure. Seems that I’m Chuck Berry‘ is all he needed to say and do, because the crowd cheered anything he did no matter how half arsed it was. It ended up more like a dreary family sing a long than a performance.
