I also enjoyed the "Live in Concert" LP, Monty. On the Bobby Darin theme, I've just read about the huge irony of Hardin's only chart hit (no. 50 on Billboard 100) having been written by...Bobby Darin!
"Simple Song of Freedom" - had no idea it was a Darin composition until you posted, CT. Neither did I realise it was Hardin's only hit.
