I used to think the lyrics to the song "Shout" (when I heard it sung by Edith Bowman on Celebrity Fame Academy, I have a copy of that) went
"I still remember when I used to be your nineties whore"
Instead of
"I still remember when you used to be nine years old"
I could not understand why a 15 year old would sing such a thing - especially seeing as the nineties had not happened when it was released!
