If i missed any chords tell me so i can put it up :]

If you want to do the version like the movie
the Intro goes:
F#m E Dm A(or Asus2 if you want)
F#m E Dsus2

Other than that here is the song.
It's pretty basic and easy if you've played guitar for atleast a couple months.

[Intro]
Asus2 E Dsus2
Asus2 E Dsus2 Dsus2

(For people who requested on youtube, here is the intro tab)
[Also, on a small note; whenever I put three lines in a row, it means strum. Usually
down up down'. If it's still confusing; then leave a comment requesting for a video
and I will post one on youtube.
