The Asylum Street Spankers do a great one entitled "Lee Harvey Was A Friend of Mine."

No, it's not a song of praise for assassinating JFK -- it's a conspiracy-buff's lament for an innocent man who was framed and quickly murdered.

For those not already familiar, the Spankers are based in Austin Texas and are perhaps the most militantly acoustic band in the world, distaining the use of all microphones, amplifiers, etc. Makes it a bit difficult to record an album, of course -- for one CD, they went with one microphone suspended from a hotel ballroom ceiling. This for an emsemble numbering anywhere from five to a dozen members at any given time.
