As mentioned in the Notes section, Jimmy O'Neill, in his opening intro, announces that this is the "final Shindig." (This is actually the second to the last show).
Watch for Brenda Holloway to make what appears to be a premature departure from the line-up during the Shindig finale. It seems maybe she thought the taping had wrapped and started to walk away, then realized she was mistaken. Still, this lady was a real head-turner!
