Hi all,  I own five different piano rolls of "Ching Chong".  I've
scanned them all to MIDI files and, inspired by the MMD discussion of
the last week, have thrown together a web page where you can listen to
them all, free of charge, in MIDI format (almost all computers should
be able to play these).  Included are versions by QRS, Connorized,
Kimball, Mastertouch, and Perfection.

The address is http://www.pianola.co.nz/articles/chingchong.html --
just click the roll labels to listen to the MIDI.
