I became a fan in 1992 when I first heard KTF. I loved it immidately.
But the funny thing is, that back in 1986 I LOVED Raise your hands (then I didn't know that it was from BJ), and after I became a fan in 1992 I bought SWW....I heard Raise your hands and thought "I know this song from somewhere, yes, it's this song I used to hear back in 1986...omg, it's BJ!" Since then I'm a die-hard fan.
