I Know It’s a Sin lyrics

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

My baby watched me from the side
Then she hung her head and cried
But I know it's a sin
It's a sin

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