I simply must find a copy of this movie. According to Amazon it's not available on DVD. Drat and double drat! As if the monkey on the poster wasn't enough - "More fun than a barrel of people", indeed! -- it apparently also features a ten-foot tall computing robot named THINKO, Vampira, a Carradine (John, the Kung-Fu patriarch!) and even a Conway Twitty cameo. Cowboys, robots, vampires, monkeys and strippers - it's like the world's greatest AiT / Planet Lar project.
I couldn't find a picture of THINKO that wasn't thief-proof but I did find this piublicity still, which only cements my belief that I cannot die without seeing this film:
