The Body is an innovative scientific documentary film that was directed and produced by Roy Battersby (actress Kate Beckinsale’s Trotskyite stepfather) in 1970. The film’s soundtrack, composed by quirky Scotsman Ron Geesin and Pink Floyd’s Roger Waters, was released as Music from the Body. Some of Geesin and Waters’ songs made use of the human body as a sort of musical instrument. Pink Floyd were always big on using the heartbeat, but Music from the Body even used farts. One of the songs is called “More Than Seven Dwarfs In Penis Land.”

In Battersby’s film, internal cameras are used to show different parts of the human anatomy in action. The film was narrated by actor Frank Finlay and Battersby’s fellow Trotsky admirer Vanessa Redgrave.
 

 
“Sea Shell and Stone/Breathe in the Air” plays under the opening credits. If you can’t take the sight of a mother’s breast in a science doc, don’t click play, you’ve been warned, weirdo:

 
This song, “Give Birth to a Smile,” features an uncredited appearance by all four members of Pink Floyd along with Ron Geesin—who would score the group’s Atom Heart Mother—playing piano. More breastfeeding.
