Intro/Verse (0:06)
It's a bass riff, but play the bass part on your guitar like this

e---------|----------|----------|---------------------------|
B---------|----------|----------|---------------------------|
G---------|----------|----------|---------------------------|
D---------|----------|----------|---------------------------|
A----5----|-----7----|----5-----|-------5--7-7b8r7--5-------|
E-7----5--|--7----5--|-7----5---|-7---7---------------5--7--| 

This is also the verse, minus the little 7b8r7 



Then Davey does a little lead lick (0:38)

e-10---7-7---9b10r9--7-|
B-10---7-7---9b10r9--7-|
G----------------------|
D----------------------|
A----------------------|
E----------------------|

Back to intro verse Riff once more, then

Chorus (0:48)

D         G         B          Em

D         G         B          C

Then play the verse lick from (1:05) to (1:38) then repeat the Chorus

Solo (1:55)

e-------7------------------------|
B-7--10--------------------------|
G------------9b10r9--7----7--9---|
D----------------------9---------|
A--------------------------------|
E--------------------------------|x3

e-------7-----9b10(and hold)
B-7--10----------|
G----------------|
D----------------|
A----------------|
E----------------|

Repeat these two measures and that's the solo.

At (2:28) go back to the Chorus.

At (3:04) go back to playing intro/verse riff until fade.

That's it.
