Look up Vic Mizzy (https://en.wikipedia.org/wiki/Vic_Mizzy)
The “Porkarana” noise is a bass harmonica.
Mizzy (who also did the Addams Family) loved odd music.
If you ever get to see the movie “The Spirit is Willing” that’s another one by him.
Thanks for that good information and I appreciate everyone who participated in this thread. I sure know a lot more than I did several hours ago because of the wide-ranging interests and intelligence of those in FReeper(s)ville, just down the road from Pixley. :)
