Tarzan, Lord of the Jungle had ended production. Robert Ridgely was a year away from returning to Filmation to work on Flash Gordon. So, you figure, he must've been doing some primetime work to merit appearing on You Don't Say.
Producer Ralph Andrews had revived You Don't Say some months earlier, but instead of going back to NBC, where the original series aired during the 60's, Andrews went to ABC, but the show was canned after a 5 month run in 1975, only to return as a syndicated pre-primetime show, hosted by Jim Peck, as Tom Kennedy, who helmed the daytime version, was doing Name That Tune at night. Anyway, Robert uses some odd character voices in this installment from November 1978.
