You may very well think I'm completely nuts but here's my question. I attended the Met Center in June of 1972 to see/hear the Rolling Stones. Unless my mind is playing tricks on me I swear they opened the evening with an as yet unheard "Angie". I know, it wasn't released until 1973 but I can distincly remember a spotlight turning on and it was Mick by himself sitting on a stool singing the song acapella. I never saw the Stones live again until the eighties but I guess maybe they could have opened one of those shows with "Angie" but by then I would have known the song.
