Name of A Cappella Music

You are my last resort! Any one know the name of the a cappella-- voice only-- music that recurs throughout the 1976 film "The Opening of Misty Beethoven?" I've heard it might be from library tracks-- are they obtainable? Sounds like it may be a "Swingle Singers" tune-- they were well-established in 1976, when the film came out... thanks!
