Verse:
A
Two lovers, forbidden from one another
A                   E
A war divides their people
E                           A
And a mountain divides them apart
A                  E
Built a path to be together

...Yeah, and I forget the next couple of lines, but then it goes...
 

A
Secret tunnel!
Gbm
Secret tunnel!
Gbm
Through the mountain!
E                              A
Secret, secret, secret, secret tunnel!
 

-nc-
Hey, I just remembered the next couple of lines...
 

A
Two lovers, destined for one another
A                               E
But the war still divides their people
E                              A
So they build down through the mountain
A                   E
And now they can be together forever
