I've always liked this one by Anne Murray:

Could I Have This Dance

I'll always remember the song they were playin',
The first time we danced and I knew,
As we swayed to the music and held to each other,
I fell in love with you.

Could I have this dance for the rest of my life?
Would you be my partner every night?
When we're together, it feels so right.
Could I have this dance for the rest of my life?

I'll always remember that magic moment,
When I held you close to me.
'Cause we moved together, I knew forever,
You're all I'll ever need

Could I have this dance for the rest of my life?
Would you be my partner every night?
When we're together, it feels so right.
Could I have this dance for the rest of my life?

Repeat Chorus
