Somewhere Else chords & tabs

Nothing to do, and I decided to try to get this song tab, but where to find?
So I had to do the work... I think it's close (if it's not exact) to the song...
I think the chords are right... Ow, there's an observation: the Am between
parenthesis -(Am)- is optional to be played, if it seems too jard to change fast
you don't need to play, the sound is almost the same...
