Oh yes, Bill Cullen also filled in for Garry Moore on To Tell The Truth during its 1970s syndicated run,

And by sheer coincidence, one of those weeks is airing now  on Buzzr.

Also, while not bona-fide substitute hosts, both Peggy Cass and Kitty Carlisle sat in Garry's seat for the first half of an episode -- usually because they knew the person in the segment.

I think Orson Bean did once as well - something to do with a comic book artist that he knew?
