In 1984 I visited the Henry Ford Museum in Michigan.  The carousel there
had a Wurlitzer 153 organ.  I spoke with the attendant, who said that,
sadly, it had stopped playing.  I asked if I could poke around.  Given
permission I did so, and found that a hose had come disconnected from
a fitting.  I put it back on, showed the attendant what I did (so he
could do it again if need be), and the show went on -- with music.
