KPIX San Francisco complete sign-off from December 12 1977

Oldest sign-off I've found so far, from what was likely a timer recording of a late-night movie. We get the Red Eye Theatre closing, last commercials from main sponsors Body Comfort and Cal Stereo, then an audio-only news update which was common at the time followed by an editorial and religious message followed by the sign-off announcement and America the Beautiful film.

Wondering what time this was, since they had the CBS Late Movie at 11:30 then two local movies afterwards. In the 80s they were still doing all-night movies and usually signed off at odd times close to 5 AM and then running color bars for less than an hour before signing on again. I never got this on tape then because of the odd hours and it rarely came in clear enough to tape, but was stoked to find this.
