I always thought this looked like a fun song to play. It's one of my first tabs, so 
if it's not correct... But here ya go:

Intro
E ----0---0---|
B ----1---1---|
G ------------|  X12
D ------2-----|
A --0---------|
E ------------|

Play that until 0:15 and then play this:

E ----0---0---0---0------------------------|
B ----1---1---1---1------------------------|
G -----------------------------------------|
D -----------------------------------------| X2 (that ends at 0:20)
A -----------------------------------------|
E --3---2---1---0--------------------------|

(0:20-0:23)
E ----0---0---0---0-----|
B ----1---1---1---1--3-1|
G ----------------------|
D ------2-------2-------|
A --0-------0-----------|
E ----------------------|

CHORUS
...Start Wearing purple wearing purple...(0:24-0:29) Just play the C chord. The 
pattern isn't hard to figure out.
E --0---------|
B --1---------|
G --0---------|
D --2---------|
A --3---------|
E --0---------|

Start wearing purple for me now...(0:29-0:33)
E --0----------------------0--0-|
B --1----------------------0--0-|
G --0----------------------2--1-|
D --2----------------------2--2-|
A --3----------------------2--2-|
E --0----------------------0--0-|

All your sanity and wits they will all vanish...(0:34-0:37)
E --0-----------------------------------0------|
B --0-----------------------------------0------|
G --2-----------------------------------1------|
D --2-----------------------------------2------|
A --2-----------------------------------2------|
E --0-----------------------------------0------|

I promise, it's just a matter of time...
E --0---------|
B --1---------|
G --0---------|
D --2---------|
A --3---------|
E --0---------|

Verse
E ----0---0---|
B ----1---1---|
G ------------|  X12 play from 0:44-0:59
D ------2-----|
A --0---------|
E ------------|

CHOURS X1

THE NEXT VERSE DOESN'T HAVE GUITAR, But if you want to play it, just play the verse above.

Then Chorus X4 Even when he's not singing the Chorus part, And THATS IT!
