Lyrics of One if for him two if for me

I'll drive by your house sometime tonight and hope i can see you again
Have a light in your window if you are free one if for him two if for me
If he's there with you i'll drive round the block he might leave before i get back
Have a light in your window so i can see one if for him two if for me
Each time you leave i take this place but we both know i can't stay too long
So have a light in your window so i can see one if for him two if for me
