I was a little too young to have seen the Paul Lynde Halloween Special from 1976, but as a lifelong Kiss fan I knew of it. Here's a national newspaper ad that ABC ran for the special, which aired on October 29, 1976. Featured on the show were Tim Conway, Roz Kelly, Margaret Hamilton, Florence Henderson, Betty White, and of course the aforementioned Kiss.
The original Disney-produced TV series Zorro (starring Guy Williams) ran from 1957-59, but a decade after its debut on ABC it still had life in reruns. This ad for the show ran in 1967 and shows us that it was airing on WKYT-TV (channel 27) out of Lexington, Kentucky. The station started out as a CBS affiliate, switched to ABC in 1958, and moved back to CBS in 1968.
