Thought I’d share.
There are some movies better, and many much worse, but there is none quite like that one!
I saw this performed at the Sacred Fools Theater last summer. Great music and just as wacky as the movie.
I love that movie! I took a friend to a midnight showing hwere in Seattle. To this day he bitches about it :). I do wish that Shrunken Heads would come out on DVD.
I stole it on VHS from a video store WAY back in the day (like, 1986 or something)- wish I could find it now! 
Love me some Elfman brothers musicals!
Have you tried Amazon? 
I know where you’re coming from. I taped it off of a movie channel back in the '80s. Found a ‘quasi-legit’ (OK, bootleg) copy on VHS and bought it. Finally got it on DVD, and had to get the colourised version as well.
I know that FZ is on DVD (I still need to replace my VHS copy) I meant Shrunken Heads.
