Well, the LoC holdings have at least sixty-seven episodes of I've Got a Secret than neither GSN nor Buzzr have aired, and now this operation has my attention. Most are from 1954-55, during the Winston era, but there are others as well. Most notable from a historical perspective is probably the 1/22/53 episode with Monty Woolley. This is the one referenced by both Gil Fates and Allan Sherman in their memoirs, Woolley apparently blustered on live television that his "secret" was made up and forced on him by Sherman.
