This is how I play it.

Intro:

G]---------------------------------------------------------------------------|
D]---------------------------------------------------------------------------|
A]-4---4-----------------4-----------2--4---4------------------------------2-|
E]--------4-2----2-4-5-------4-5~--5------------4-2---2--4-5----2--4-5~--5---|

THEN:

G]------------|
D]------------|
A]--4-6-7-6-4-|   SEGWAYS BACK INTO RIFF
E]------------|

ONLY DO INTRO ONCE.

THEN REST OF SONG:

G]---------------------------------------------------------------------------|
D]---------------------------------------------------------------------------|
A]-4---4-----------------4-----------2--4---4------------------------------2-|
E]--------4-2----2-4-5-------4-5~--5------------4-2---2--4-5----2--4-5~--5---|

DO THIS 2X

THEN:

G]------------|
D]------------|
A]--4-6-7-6-4-|   SEGWAYS BACK INTO RIFF
E]------------|

REPEAT UNTIL END THAT'S IT
