This is a really great and fun song to play.  Great to play with a few friends on a sunny day. 

Standard tuning
No capo

The basic progression for the intro is the same as the verses.
*When an A chords appears, play it up on the fifth fret.

Intro/Verse:
A E D F#m E

Chorus:
F#m E Am D F#m E

End of Chrous and back to verse: 
D Am

Bridge (Play G on 3rd fret):

You can figure out the timing and strum.  Again, this is a great and fun song.  
Play it acoustic or electric and it'll sound great.  Greta I love you.
