The Gay Follies of Saturday Morning (partially found flexi-disc by Hustler Magazine; 1976)
The Gay Follies of Saturday Morning is a flexi-disc recording released by Hustler Magazine, an erotic magazine.
It contains cartoon characters doing homosexual acts to each-other. The only part that's available is the part with the Looney Tunes characters, presumably Petunia leaving Porky stuffing a dildo up Bugs hole. Of course, the Looney Tunes characters are voiced by Mel Blanc.
No Google results or newspaper articles cover the disc, presumably because of the inappropriate nature of the recordings. However, Looney Tunes critic Trevor Thompson of Ferris Wheelhouse has the whole disc, but it is unknown whether he'll release it to the public or not.
