In this Charles Manson documentary (I first watched off of Youtube) it ended with a song I liked. If anyone can remember a Manson documentary that ends with an actual Manson song get back to me. I thought it was actually a good song and I was interested in adding this song to my music collection.
These two are listed as having Manson songs in them. Not sure if they’re at the end, but maybe one of these is familiar?
