A Guide For The Married Man (1967)

Before he was John Williams (Star Wars, Schindler's List), he was "Johnny" Williams: talented jazz artist and up-and-coming film and television composer. A Guide for the Married Man is a 1967 comedy starring Walter Matthau and a bevy of "guest stars" illustrating the art of adultery. The music is a smorgasbord of comic, jazz, and straight orchestral styles, with a title song written by Williams and Leslie Bricusse, performed by The Turtles! Stereo, with outtakes.
