The song That's All That Matters is performed by Jerry Lee Lewis .
I know I'm not your first love
They're just a past memory
I'm the one who's got you now
And that's all that matters to me
I know other arms have held you
But I'm not jealous of these
Mine are the arms that hold you now
And that's all that matters to me
I came alive when you came along
Yes, you've brought life back to me
And I don't care what's in your past
You're as far as I can see
I know other lips have kissed you
And I know you've been thrilled and pleased
Mine are the lips that kiss you now
And that's all that matters to me
Yes mine are the arms that hold you now
And that's all that matters to me
