I Know It's a Sin

I know it's wrong, the things I do
The way that I mistreated you
But I know it's a sin, it's a sin

She stood and watched me from the side
Oh, she hung her head and cried
But I know it's a sin, it's a sin

My baby told me, yeah, from the start
She said, "Darling, you breaking my heart"
But I know it's a sin, it's a sin
