I've noticed the "Coundown" on recent WML? episode notes, most recently #130:
(4) GARRY MOORE "IGAS" COUNTDOWN WATCH - 17 SHOWS TO GO: Right after the March 24, 2008 airing of tonight's show, GSN repeated a "live from New York" edition of "I've Got a Secret," with host Garry Moore and panelists Bill Cullen, Betsy Palmer, Henry Morgan and Bess Myerson, which was originally broadcast on February 24, 1964 -- which was 44 years and 1 month from this most recent GSN airing. The celebrity guest was Morey Amsterdam. - W-B (2008 )
Is GSN replacing it? Or do they have to skip to the Steve Allen "IGAS" episodes for reasons of cigarette sponsorship?
