I seem to remember him singing this.....

OH LOVE THIS IS MY SONG
A SERENADE FOR YOU
AND MY LOVE CAN NOT BE WRONG
AND MY LOVE IS STRONG FOR YOU

I CARE NOT WHAT THE WORLD MAY SAY
I LOVE YOU MORE AND MORE EACH DAY

SO LOVE THIS IS MY SONG
MY SERENADE OF LOVE FOR YOU

I may be wrong, it's been many many years I hope this helps.....
