Hey guys ever since I heard this song I've wanted to play it on guitar. Many thanks to
'Kris' who I learnt the basic part of the tab from, which was great but I noticed a
couple of minor errors so I wanted to post my version.
Note:The chorus is not what the guitar actually plays but I find it's better for just a 
voice with guitar.
-Also, the sixth and seventh notes of each bar (not tab) are played faster than the others.
