From the recording Becoming

My humble tip-of-the-hat to the genius of Brian Wilson. Simply one of the greatest pop songs of all time. I came up with the words in the middle, replacing the "ba-ba-baaaa" part. Also I took the tempo just a tad slower.

Lyrics

God Only Knows

I may not always love you
But long as there are stars above you
You'll never need to doubt it
I'll make you so sure about it
God only knows what I'd be without you

If you should ever leave me
Though life would still go on, believe me
The world could show nothing to me
So what good would living do me
God only knows what I'd be without you

If there ever was a time I needed you to say
You’re here to stay
‘Cause God only knows what I'd be without you

If you should ever leave me
Though life would still go on, believe me
The world could show nothing to me
So what good would living do me
God only knows
God only knows
God only knows what I'd be without you
God only knows what I'd be without you
God only knows what I'd be without you
Brian Wilson/Tony Asher
