Lyrics

I wait ed till I (E)saw the sun.

(D7)I don’t know why I (G7sus)did n’t come.

(C7)I left you by the (E)house of fun.

(D7)I don’t know why I (G7sus)did n’t come.

(C)I don’t know why I did n’t (G7sus)come.

When I saw the (E)break of day,

(D7)I wished that I could (G7sus)fly a way

’stead of kneel ing in (E)the sand

(D7)catch ing tear drops (C)in my hand.

My (Am7)heart is

drenched

(G7)wine,

but (Am7)you’ll be

(G7)mind for

(G)er.

Out a cross the (E)end less sea,

I would die in (G7sus)ec sta sy.

But I’ll be a (E)bag of bones

(D7)driv ing down

the (G7sus)road a lone.

(C)My (Am7)heart is

drenched

(G7)wine,

but (Am7)you’ll be

(G7)mind for

ev er.

Some thing has to (E)make you run.

(D7)I don’t know why I (G7sus)did n’t come.

(C)I feel as emp ty (E)as a drum.

(D7)I don’t know why I (G7sus)did n’t come.

(C)I don’t know why I (G7sus)did n’t come.

don’t know (D7)why I (G7sus)did n’t (C)come.
