 This was known as the "Night of the Big Switch" due to the fact that  the regular panel of Tom Poston, Peggy Cass, Orson Bean and Kitty  Carlisle traded places with the "Ive Got a Secret" panel of Bill  Cullen, Betsy Palmer, Henry Morgan and Bess Myerson. Ironically,  Bill Cullen would go on to become a regular panelist on the  syndicated version of "To Tell the Truth" (1969) and Kitty Carlisle  and Orson Bean were at one time panelists on "Ive Got a Secret"  (1952).
