Mama Cass in HR Pufnstuf video

Wow! This is so awash in 70′s camp/queer sensibilities, I don’t even know where to begin. As a kid, I absolutely adored HR Pufnstuf. So this video features a bunch of witches (including not only Mama Cass, but Martha Raye as the boss witch.)
Geez. If this were any gayer, it would be fisting itself in a sling at the Mineshaft. While discussing opera.
