When I went to work in '72, I was on the mobile production team that did the TV show "The Midnight Special". You remember the one with Wolfman Jack. He was the host that everybody remembers. Our production crew went to a lot of concerts and venues until the early 80's. We put every concert on video tape for playback every Friday night after "The Johnny Carson Show". What I liked about it was the fact that we got to see every act twice because they performed the exact same set during a second concert usually the next night. That was so we could edit between sets to get a cleaner "take" on each song. We recorded acts like The Beach Boys, Elton John, The Jacksons, The Bee Gees, Genisis, REO Speedwagon, ABBA, and KISS to name a few that I can remember. I bet we recorded over 500 of the most famous acts. Now to my favorite concert...easy choice....Dolly Parton. While I was watching her, I didn't even realize she was singing.
