I bought a fairly youthful QRS roll recently in an antique store,
bearing the title "Q-168 Darktown Strutters Ball (The original QRS
164)".  After I got it home and looked at the first part of the
punching, it didn't seem to match the QRS 164 scans so amply
represented at IAMMP, of which this is a good sample:

http://www.pianorollmusic.com/doesigns/midifiles/PDfiles/QRS-164_DarktownStrutters%27Ball,The(1916)_eRollMIDIWexp.mid 

(Ignore the copyright year in the filename, the piece wasn't written
until 1917.)

After scanning, I confirmed that it's quite a different arrangement,
and much less pleasing to my tastes than the supposedly contemporaneous
(~1917) QRS 164.  It certainly is missing the Kortlander "kick".  I'm
left to wonder just how jumbled the QRS archives had gotten by the time
they started re-issuing the old hits.
