First tab, yay!

The whole song is pretty much four chords.
Except for the verse, if you don't like Bbm, you can use G or Gm.
Whatever you like.

Am, C, Dm, Bbm

Am (x02210@1)                       C (x32010@1)   Oh baby baby, have you seen Amy tonight?

      Dm (xx0231@1)                           Bbm (x13321@1)     Is she in the bathroom, is she smokin' up outside? (Oh!)

etc.

Same for bridge and chorus. Good luck!
