Perhaps you've heard of a fellow by the name of K. Gordon Murray who brought you a little cinematic gem called Santa Claus (and also 'Robot vs. The Aztec Mummy' and the three shorts that make up 'Santa's Village of Madness')?
Well, Puss in Boots is another batsh*t insane childrens' movie he imported from Mexico, recut and redubbed by Murray with random musical numbers filmed at Pirate's World or wherever the Santa's Village stuff was shot tacked on to pad the runtime. This is easily the craziest thing he's imported next to Santa Claus vs. The Devil. Just take a look at the trailer, I'll wait...

Unfortunately, while the original uncut versions of these films Murray imported from Mexico and Germany are pretty easy to come by, the American dubbed versions are extremely rare because the IRS seized all his pictures due to tax evasion and he died of a heart attack before he and his family could sue to get them back. I don't actually know how that works in terms of copyright, but I believe since Santa Claus ended up in the public domain, his other films probably are too.

The original prints of Murray's films are effectively gone, and the company that held the 16mm versions that were used to release a few of his pictures on VHS during the mid 90's (round about the time MST3K picked up Santa Claus) went bankrupt in the early 2000's and liquidated their entire inventory to the public.

Very rarely, a transfer from one of these 16mm prints shows up and I actually happen to have a copies of two of them. The Golden Goose (1969) and Puss In Boots (1961). The Golden Goose has already been posted to archive.org (https://archive.org/details/the-golden-goose-1969), but my copy of Puss In Boots has some extremely bizarre audio issues that I want to attempt to clean up prior to posting.
If I do manage to get it fixed or if you find a better copy through other sources, it's well worth riffing.
