歌曲歌词
Waited 'til I saw the sun
I don't know why I didn't come
I left you by the house of fun
I don't know why I didn't come
I don't know why I didn't come
When I saw the break of day
I wished that I could fly away
Instead of kneeling in the sand
Catching teardrops in my hand
My heart is drenched in wine
But you'll be on my mind Forever
Out across the endless sea
I would die in ecstasy
But I'll be a bag of bones
Driving down the road along
My heart is drenched in wine
But you'll be on my mind Forever
Something has to make you run
I don't know why I didn't come
I feel as empty as a drum
I don't know why I didn't come
I don't know why I didn't come
I don't know why I didn't come
