I am always fascinated by The Beatles live performances. They were playing giant halls and stadiums using PAs and guitar amplifiers far less powerful than what we see in 100 person clubs now. They couldn't usually overmatch the screaming. When I saw them in '66 in Seattle (their second to last concert performance ever), it was a murky jumble of sound, and the girl's screams won. It was all made up for by just being in their presence for 25 minutes (yes, that's how long they played, but still, we got our $5 worth). It is amazing how good they actually sounded, with the deck totally stacked against them...
