@PNS The walrus was Paul. They said so in a subsequent song. Goo goo ga-jube. (And that's the official spelling in the lyrics sheet).
The song with the K sound scat singing in it is Rock and Roll Hoochie Koo (Not 2B confused w/sports jam Rock and Roll Part 2) sung by guitarist Rick Derringer along with Texas albino legendary keyboardist (and Scientologist) Edgar Winter. Yeah the 70s Frankenstein jam song guy, not to be confused with his Texas albino blues legend guitarist bro Johnny Winters.
