==================

I have got you under my skin
I've got you deep in the heart of me
So deep in my heart
You're nearly a part of me
I've got you under my skin
I have tried so not to give in
I have said to myself this affair
Never gonna go somewhere
But why should I try to resist
When baby I know so well
That I've got you under my skin
I would sacrafice anything
Come what might
For the sake of holding you near
