Ok so this song is pretty simple and you're only using the 4th and 5th strings all the 
way through.

Intro:

e|--------------~----------------------------------------|
B|-------------------------------------------------------|
G|-------------------------------------------------------|
D|---4---5---4---2--0--2---4---5---7---9-----------------|
A|---5---7---5---3--2--3---5---7---9---10----------------|
E|-------------------------------------------------------|


Verse:

e|--------------~-------------------------------------------|
B|----------------------------------------------------------|
G|----------------------------------------------------------|
D|---4---5---4---2--0--2---4---5---7---9---7---5---4--------|    X2
A|---5---7---5---3--2--3---5---7---9---10--9---7---5--------|
E|----------------------------------------------------------|


Chorus:

Ok so the chorus gets a little fancy but its really easy it goes like this:

e|--------------~----------------------------------------|
B|-------------------------------------------------------|
G|-------------------------------------------------------|
D|-----4-4-------5-5-------7-7-------9-9-----------------|
A|---5-----5---7-----7---9----9---10-----10--------------|
E|-------------------------------------------------------|

It plays through that a bunch.
Thats basically the whole entire chorus but at the very end before you go back into the 
verse it goes all the way through with the fancy stuff and then instead of playing the 
10,9,9,10 part you just play:

e|--------------~----------------------------------------|
B|-------------------------------------------------------|
G|-------------------------------------------------------|
D|---9---9---5---4---------------------------------------|
A|---10--7---7---5---------------------------------------|
E|-------------------------------------------------------|


So that is the entire song. After the 2nd chorus though you might get a little confused 
but its all in tabs and the notes you play don't ever change so just play around with it 
a little bit and make it yours and have lots and lots of fun! (:
