I just discovered this great thread. Al Stewart lining up an all-nighter when Simon and Garfunkel were playing the Royal Albert Hall, and Paul Simon calling in about 3am to sing a couple of his new songs, like Save the Life of my Child which sounded so rich, so dramatic, so strong and even, so beautiful, that I could barely believe he was just a voice and guitar like everyone else - a Martin, but other people played Martins - or Davey Graham's all-nighters when he just got back to London from Greece, playing Monk, Indian ragas, blues, Bulgarian shepherds' bagpipe tunes, old English, every imaginable style, with Roy Harper calling in about 3am wearing a green and orange check three-piece suit and battered top hat, singing his asylum song Committed, chorus: life is such monotony without a good lobotomy; everything new, or unsuspected combinations of old things showing that they worked too. Right place right time, great to be there then.
