I think there's a quick Em - G change in the first line of the chorus ("Don't you ever
forget about me"), so yeah :) Anyways, it's my first tab, so be nice, and have fun with
the song! Some mistakes here and there, but meh :P It's a blast to play and sing, and 
chicks will dig you for it ;)

         GBut (320003@1)I'll do it.

  GI (320003@1)hope it's because you can't stop thinking about
    Dthe (xx0232@1)reasons why you close your eyes,
