In 1968, the Rolling Stones filmed The Rolling Stones Rock and Roll Circus. The Stones played, Jethro Tull played, Taj Mahal played, John Lennon and Yoko Ono played, etc.
And oh yeah, The Who played. Boy did they play. I watch this from time to time. It’s a multi-part song that you don’t think they should be able to execute live, but they do.
Just the best.
