I was watching the 1932 Marx Brothers movie "Horsefeathers", and in the
Speakeasy scene (the password is 'swordfish') there's a coin instrument
that plays three songs clearly.  I made a small (3.5 minute) streaming
windows-media video clip of the scene:  http://www.amica.org/tmp/hf.wmv

Can anyone positively identify the instrument from the audio?  To me
with the reiterating xylophone and wooden block, it may be a Cremona,
but I'd like to find out for certain.

And can anyone identify the names of the three tunes clearly heard in
their entirety?  Or even the roll number itself?
