Am--C--D--Dsus4 for the chorus and the "Lines are forming..." part.
THE UNDERTOW
Em C D Dsus4 Bring back the innocence lost Em C D Dsus4 It may be later than you think Em C D Dsus4 There's new places to explore Em C D Dsus4 But the old ones return tomorrow
Am C D Dsus4 Lines are forming all around Am C D Dsus4 Here them cry out above our heads
Em C D Dsus4 Divide the years apart Em C D Dsus4 The past will crumble like a shell
Chorus: (use the same Am--C--D--Dsus progression as above)
I'm being tempted hear the call
Try to be careful and I don't know why
One hundred years maybe more
I'm being tempted and I don't mind it
(Resume the Em--C--D--Dsus4 progression for this verse)
