I have a disc called Bloopers Bonanza 1960’s that has a TOS Blooper section that starts out with a Gorn on a microphone. Would this be of some use to you? It is a 16min 55sec piece.

Holy crap…I had forgotten that I actually have this!
Quality is pretty low (fuzzy, muffled, and very poor color), but better than a lot of the YouTube uploads I think. But I’d really love to see a copy that was clearer and closer to the source.
