The tune in the YouTube clip that Ben Waterbury asked about in
yesterday's MMD is "The Bonnie Briar Bush" (Joseph H. Ellis).

It is playing from a Wurlitzer Style 125 roll.  On another video,
Andrew Barrett identified the same organ as a 46-key Gavioli,
converted to play Wurlitzer Style 125 music rolls.
