Found,by accident, a website called Supermanbobholiday.com
It turns out he is a home builder in the Pocono Mountains of Pa. The website has a clip of him on I've Got A Secret with Steve Allen. He (Bob)is in Superman garb
I remember hearing Christopher Reeve talk about how Bob Holiday had set up a table outside the theater to sign autographs and such when Reeve was in Fifth of July on Broadway in the 1980s. I always thought that was a sad, strange story. Kind of sucks when the highlight of your career is a flop from when you were young, but I really enjoy his performance on the cast album and can't imagine why he didn't get any more work. I really love the cast album of the show and wish I could see it (I've managed to miss all of the concerts/readings).
