This is my first tab, i was taught this song by my friend i went and listened to it and
then changed his way (The second way) to a better sounding one and im pretty sure its
right if not Pm me. Here is the main chords for the song, there are two ways to play it, 
and i will show both of them.

Am C/F# C/G G

The second way may be a bit easier;

Am F C G

Personally i think the first one sounds better but i have had people say the second is
better. Anyway Enjoy :P
