In the mid 60's we had a dance every Saturday night for teens. It always ended with the same song. Instrumental; brass horns with a long single horn then into a slow dance song. I have asked and looked around. Some friends think it is called "Last Dance" but I have not found the right one if that is it. "Last Date" is close but that is not the tune and Last Date was piano. I would love to find this for our 40 year reunion.

Maybe a couple of Mar-Keys tunes that were usually played as a medley: Last Night/The Night Before at least I think that was the name of it.
