Ruby Duby Du in Key Witness film (1960)

A theme song in the movie. Written and played by the Charles Wolcott band. Ruby is the girlfriend in the film, and the theme is played in three different places. That's Jeffrey Hunter and Dennis Hopper in the video.
Besides Wolcott's single, there was also an instrumental
by Tobin Matthews ( • Ruby Duby Du - Tobin M... )
and a sparkling vocal by Joanie Sommers ( • Joanie Sommers sings R... ) .
