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
Oh baby baby, have you seen Amy tonight?
Is she in the bathroom, is she smokin' up outside? (Oh!)
etc.
Same for bridge and chorus. Good luck!
