This track was seemingly everywhere in the early 70s; commercials, bumpers, adult movies.
There's a short snippet here at the 8:34 mark... Can anyone identify it?
This actually isn't a library track. It's a track recorded by the rock group Blood, Sweat and Tears, "Variations on a Theme by Erik Satie (1st and 2nd Movements)".
Wow! Thanks! :) That explains why it was everywhere.
