Just a thought -- The microphones on digital and other video recorders
are usually pretty good at recording the noise your hands make holding
the recorder or camera, but not much else.

Suggestion: buy a medium-quality microphone and an extension cable.
Place the microphone on a tripod, a stand or anything that's handy at
an optimum distance from the instrument and make your picture and audio
recording.  (For nickelodeons, orchestrions and band organs place the
microphone around six to ten feet away.)  It makes a difference.
