At the very end of the 1955 Ealing Studios comedy, "The Ladykillers"
(with Alec Guinness, Herbert Lom, Peter Sellers, Franky Howard, etc.
etc.), an unseen musical box is played.  Does anyone know the make
of the musical box and the tune it plays?  I would guess that it is
probably a disc musical box.
