Lyrics:

I've been through some hard love
Sweet love, impossible love, deep love
But there was always a hitch
Something couldn't be fixed
A bit out of tune with ending, it soon

And just when I felt I had enough (had enough)
And I thought my life just wasn't living it up
You came to me so magically
Giving me love in the key of C

I've been impressed
Depressed
Satisfied
Completely denied

But with you, it just feels so right to me (right to me)
We both came together so easily (easily)
And I can't believe that I love you (and)
You love me, love in the key of C

Love in the key of C
You're my life's sweet harmony
It's the key of Amazing Grace
'Cause you save my life
When it was all the way down
Your gentle love turned my life around

'Cause with you, it just feels so right to me
We both came together so incredibly
And I can't believe that I love you (and)
You love me (thank you, God)
Love in the key of C
Love in the key of C
