Ed Sullivan DVD: Big Bird's Dance

[Splurge]

For those of you who've seen this, I'm curious about the weird background music for "Big Bird's Dance". I've heard that music on TV for many other shows, particularly in the 70's, which leads me to believe that it's one of those things on records for background music similar to sound effects recordings.

Anyone know how I could find out what the name of the music is?

(Or am I just talking utter nonsense? )
