Yeah, it's just my educational guess. Who knows? It could just as easily be one of their JW tracks, which one can find on apm. Sometimes really elusive tracks just turn up where you'd least expect them to be. I haven't looked into the entire JW Theme Music catalog to know for sure though.
Interesting side note on Video Moods though. One of the cues which recently surfaced, "Watch for the Manhole" by Ward Sills was used in another vintage cartoon, "Linus The Lionhearted"
Particularly in a previously lost Rory Raccoon segment, "Bye Bye Bad Bird" (at 2:20)
https://youtu.be/m6AXsmgnV3sI also used it in my own cartoon after it resurfaced (

If I find any more three stooges cues, I'll share them on my alternative channel, but so far there's no word on any video moods 78s for sell on discogs or ebay.
