watch the video for timing and struming. since the whole 
song repeats all you need to know are some simple chords:

C#m, A, B

intro:
the intro to the song is a C#m with the alternation 
of removing the pinky finguer and the middle finguer 
of the fret board and strumming.
the figure should look something like this:

e|---4---4---4---4---4---4--|
B|---5---5---5---4---4---5--| (this part is a little 
G|---6---6---6---6---6---6--| tricky, so experiment with it)
D|---6---4---4---6---6---6--|
A|---4---4---4---4---4---4--|
E|--------------------------|
 
the intro then continues into the A chord and B chord

intro twice...

I'm not sure about the tunning, I play it in standard 
and it sounds good, although, out of personal 
preference I slide everything to start from the 
third fret, but again thats just personal preference.
