I remember listening to this song many eons ago and taking an instant liking to it. Fortunately I heard it again the other day while watching a TV series, and managed to track it down on the internet.
The song contains no actual words, but somehow becomes catchy. Written by Piero Umiliani famous for spaghetti western and soft core porn scores, it has featured in many films and television series, including The Muppet Show. If it sounds familiar, yep that’s where you heard it.
