Thanks to Gerald Bamford:
“Which unreleased songs or takes of Bob's should be part of a future Bootleg Series? I would certainly recommend an outtake from Under The Red Sky - 'TV Talking Song' - which fairly rocks along and should have been included somewhere on Tell Tale Signs
“I learn from Michael O'Shea (via John Baldwin) that the French edition of Rolling Stone has an 8-page Bob feature including an article on a fantasy Bootleg Series vol. 9 by Frédéric Lecomte, which picks out 25 unreleased items.”
