But the end music had complete gibberish for lyrics.

“Before you get excited about finding those long lost lyrics, the actual answer is – there are none! Tom Chehak, a first season writer who was present at the Atlanta recording session of the theme, recalls how Tom Welles, theme writer, suggested to Chehak and Hugh Wilson a closing theme for the song. According to Chehak, the singer just started blarring out a bunch of nonsense words; if any of them were actual words, they’re lost to history. Indeed, Chehak recalls how great they all thought it would be to leave fans guessing forever – looks like they got their wish.”
I always considered the MTM kitten meow part of the song.
