The Italian singer Adriano Celentano sings a song with fake words to sound like English. More information on this (and where I found it at) is here: www.bakadesuyo.com
Toberoni translated Adriano Celentano's gibberish lyrics into comprehensible English.
I found out more information on the song. It is titled "Prisencolinensinainciusol", and was released in 1972. More information on the song is found at Wikipedia.
