As far as the Play-Rite Wurlitzer band organ rolls are concerned,
I seem to recall they edited and combined the contents of old rolls.
They were not a direct copy of the originals.  The length of the tunes
were shortened and the playing order was scrambled.  This what
Play-Rite copyrighted, not the work originally done by Wurlitzer.

 [ That's an interesting point.  Play-Rite combined two 5-tune rolls
 [ into one 10-tune roll, interleaving the tunes so that the paper
 [ speed was proper during playing.  Play-Rite also shortened the
 [ overly-long tunes so each one played for a little less than 3
 [ minutes, just as with Wurlitzer's own 10-ten rolls.  The end product
 [ was well-received because the shortened tunes are no longer boring!
