This is one of my first tabs. I thought I'd introduce a tabbed out version, played to 
the melody of the lyrics. So here we go (:

Standard Tuning (EADGBE)

Verse 1:

E------------------------------------------------------------------|
B------------------------------3-3-1-1---------------------3-3-1-1-|
G------2-----2-----2----2--2-2---------2------2-----2--2-2---------|
D---0-----0--0--0-----0-0------------------0-----0--0--------------|
A------------------------------------------------------------------|
E------------------------------------------------------------------|

E-----------------------------------------------3-2-------3-2p0----|
B----------------3-3-1-1-3p1--------------3-3-3-------3-3-------3--|
G-2-0-2p0----2-2-------------2-----2----2--------------------------|
D---------2---------------------0----0--0--------------------------|
A------------------------------------------------------------------|
E------------------------------------------------------------------|

Pre-Chorus

    Dsus      D                                Cadd9     G
E------3p2-/---------2222-------------2222---------3------3---------|
B-----3---3/-----3-3------3-3-----3-3------3-3------3------3-3------|
G----2-----/-2-2--------------2-2-----------------0--0------0-------|
D---0------/-------------------------------------2-------0----------|(x2)
A----------/------------------------------------3-------2-----------|
E----------/-------------------------------------------3------------|
          (x2) starts here

Play Chorus with whatever strum pattern you like, It's D, C, G just like the chorus.

Verse 2:

E------------------------------------------------------------------|
B------------------------------3-3-1-1---------------------3-3-1-1-|
G------2-----2-----2----2--2-2---------2------2-----2--2-2---------|
D---0-----0--0--0-----0-0------------------0-----0--0--------------|
A------------------------------------------------------------------|
E------------------------------------------------------------------|

E---------------------------------------------------3-2-0----------|
B----------------3-3-1-1-3p1------------------3-3-1-------3-0------|
G-2-0-2p0----2-2-------------2-----2----2-2-2-----------------2----|
D---------2---------------------0----0--0--------------------------|
A------------------------------------------------------------------|
E------------------------------------------------------------------|

E-----3-2-------3-2p0----|
B-3-3-------3-3-------3--|
G------------------------|
D------------------------|
A------------------------|
E------------------------|

Then repeat Pre-Chorus, Chorus, and so on. The rest of the song is the same. I think 
there's a bridge but I'm not 100% on how it goes.
