I lost count of how many dances I went to as a teenager and young adult that ended with Led Zeppelin's "Stairway to Heaven." The quintessential last song.
Once in a while they played Lynyrd Skynyrd's "Free Bird," which I loved, even though it was a bit awkward when it shifted from a slow dance to a fast dance part way through.
But that was not anywhere near as awkward as the time a guy I didn't know and who was much shorter than me asked me to dance. I said yes, because I didn't want to be rude. In the middle of the dance, he wiped his nose with the back of his hand without letting go of mine.
When he asked me for another dance, I turned him down.
