I can’t find it but I found this. Kenny Rogers & Sheena Easton - We’ve Got Tonight http://www.youtube.com/watch?v=ogWcJeV7r4Y&mode=related&search=
That’s a good one too!
We also like Mary Chapin Carpenter’s Grow Old Along With Me.
Incidentally, John Lennon wrote the lyrics!
Grow old along with me
The best is yet to be
When our time has come
We will be as one
God bless our love
God bless our love
Grow old along with me
Two branches of one tree
Face the setting sun
When the day is done
God bless our love
God bless our love
Spending our lives together
Man and wife together
World without end
World without end
Grow old along with me
Whatever fate decrees
We will see it through
For our love is true
God bless our love
God bless our love
