Not really a show, but Im familiar with the old CBC (canada) sign-off. Wasn’t really my bed time either, I have insomnia disorder, I would just read books after the tv went off-air for the night. I’m also familiar with the CBC sign-on, and the first program on in the morning was 100 Huntley Street, followed by the PTL Club, before Jim and Tammy Faye went to jail.
