Definitely remember that show!
It began at 10:30 PM (or later, depending on circumstance) Friday on Channel 11 Green Bay, which was ABC at that time (now it’s Fox). Had a theme song (Well its Friday night …), snippets of which I remember even today. Doug Heim was TJ (Television Jockey). ANT was All Night Theatre (The show’s original title was TJ and the All Night Theatre). It ran until about 8:00 AM Saturday. On several occasions, I watched the entire show.
One night Heim announced at about 3:00 AM, completely unexpectedly, the TV execs, in their infinite wisdom, had cancelled his show.
That was it. No more TJ. No more ANT.
