I listened to the Caribou album all the time as a kid and knew the words, but thought it was French. Turns out it was all made up as a joke by Bernie Taupin to sound like gibberish, and means nothing.
I have no idea what the words are in Benny and the Jets and also Pour Some Sugar on Me, lol. I suppose I could look them up now but I just continue to sing the nonsense that I've always sung.
