>>126890567nah that was Joe Cocker and Canned Heat. seasoned cover band/song and dance men. easy lay up for sure but it's true.
every other act used extensive overdubs for public release (CSNY) or stopped their set from being filmed/recorded (the Dead) or haplessly phoned it in (the Band/CCR) because being exposed as frauds was not cool during the proficient blues rock environment.
the Who transcended the event and shouldn't be lumped in with the rest of the paycheck hacks.
that jealous jew Albert Grossman seeing Led Zep live before this and shitting his diaper knowing they would upstage his and everyone else's acts gifted the Who as the transcendent band of the event.
