Dave Van Ronk's "Last Call": I haven't done it lately; it is a 20th century composition written in a very old-fashioned style that demands to be sung unaccompanied or not at all.

The story is that Dave, Leonard Cohen, and Joni Mitchell were drinking together late into the night, and this song's lyrics were found in the morning in such nearly-indecipherable script writing that no one's handwriting could be recognized. The other two apparently let DVR have it; perhaps he wrote the melody (or "chose" it from the traditional airs in his memory bank).

My usual closing number since August 2005 has been "Do You Know What It Means to Miss New Orleans." I worked up my arrancement while in Katrina exile, badly missing New Orleans myself at the time.
