What to play at the very end?

[mroldies]

I wonder what an oldies DJ (oldies presenter) should play as the last song when he retires after many years
of working in a radio station...
"A Touch Of Velvet - A Sting Of Brass"?
"Sleepy Shores"?
"River Deep-Mountain High"?
Or simply "Roll Over Beethoven"?

Do you have any interesting tips?
