Question about the "Disco Snuffy" sketch

[YellowYahooey]

I saw the "Disco Snuffy" sketch today, and I have noticed that there was use of instrumental versions of music by licensed recording artists. I did notice that one of the tracks was "He's the Greatest Dancer" by Sister Sledge (incidentally, when the sketch was first broadcast on March 12, 1979, the song had just debuted on the Billboard top 40 at #38 the previous weekend), but I'd like to ask, what was the other disco track used in the latter part of the disco scene?

I know about the disco version of "Rubber Duckie", but that was not what I was referring to. I was referring to the track being heard after the instrumental version of "He's the Greatest Dancer" was heard.

Play that video again and tell me what you hear.
