I started singing this while my mom was listening and she is Astonished by the fact that I know the song. Dad used to sing it all the time mom, when he missed you.

Nothings gonna change my love for you
You ought to know by now how much I love you
One thing you can be sure of
Ill never ask for more than your love
Nothings gonna change my love for you
You ought to know by now how much I love you
The world may change my whole life through
But nothings gonna change my love for you
