Though not technically a song BB still sings it as a warm up in the episode Phantom of the Hip-Hopera and it could be a full song that the audience just never got to hear in full.
Kurtz also sings a version of this song in the episode Gloveball Been Very Good to Me.

Whoaaaaoa yeah, let the tone shake you to the bone knock you off your feet, gotta keep on rolling, let your soul lose control again make your self complete yeahhh yeah yeah yeahhhoooooo
