“Nod my head, so dumb with love…”
E|-------------------------------------------------------------------|
B|--------12-9-10-9--12-9-10-9--12-9-10-12--10-9-7-------------------|
D|-------------------------------------------------------------------|
G|-------------------------------------------------------------------|

Repeat the above riffs once more.

Chorus
“Coming Back”
 This part is just switching between the 9th and 7th fret on the B String.
E|-------------------------------------------------------------------|
B|--------9-7--------------------------------------------------------|
D|-------------------------------------------------------------------|
G|-------------------------------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

“You come out and say the word…”
This riff is played the first and third times:
E|-------------------------------------------------------------------|
B|--------9-7------------------9-7-----------------------------------|
D|-------------9-6---6-9---6-9-----9-6-------------------------------|
G|------------------9----9-------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

On the second time it ends slightly differently:
E|-------------------------------------------------------------------|
B|--------9-7------------------9-7---7-------------------------------|
D|-------------9-6---6-9---6-9-----9---------------------------------|
G|------------------9----9-------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

When played the fourth time, it stops abruptly about halfway through:
E|-------------------------------------------------------------------|
B|--------9-7--------------------------------------------------------|
D|-------------9-6---6-9---------------------------------------------|
G|------------------9------------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

“Coming Back” (Heavier)
Really not too sure about these but I think it might be these power chords or something similar.
E|-------------------------------------------------------------------|
B|-------------------------------------------------------------------|
D|--------2-----4----------------------------------------------------|
G|--------2-----4-----2----------------------------------------------|
A|--------0-----2-----2----------------------------------------------|
E|--------------------0----------------------------------------------|


Outro (“Your Eyes”)
This is the bass line in outro (you should be able to work out the rhythm yourself):
E|-------------------------------------------------------------------|
B|-------------------------------------------------------------------|
D|-------------------------------------------------------------------|
G|-------------------------------------------------------------------|
A|--------2------5------0--------------------------------------------|
E|-------------------------------------------------------------------|

I don't think there really is a guitar part for this the initial part of the outro but
it sounds OK if you play along with these power chords:
E|-------------------------------------------------------------------|
B|-------------------------------------------------------------------|
D|--------4------7------2--------------------------------------------|
G|--------4------7------2--------------------------------------------|
A|--------2------5------0--------------------------------------------|
E|-------------------------------------------------------------------|

At some point during the “Your Eyes” outro part this comes in with a really weird effect:
E|-------------------------------------------------------------------|
B|--------7----------------------------------------------------------|
D|----------6---6hold------------------------------------------------|
G|------------9------------------------------------------------------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|

And that's basically it. The structure of the song is:
