The Who would be top of my list as well. Would love to have seen Quadrophenia played live.
That was my first concert...1974, Madison Square Garden. Ears are still ringing.
Quadrophenia was a dud live unfortunately. They had to go back to playing Tommy at their live gigs.
But the one Who concert I would have loved to have seen was the 1970 Isle of Wight Concert, because they included the best songs, that didn’t make it onto “Who’s Next”, like “Water” and “Naked Eye” and “I Don’t Even Know Myself”.
