I received a flyer announcing another concert involving playing music
rolls on the Salomons Welte Organ in Kent, UK.  The concert has been
arranged for Thursday, 22 March, 2007, at 7.30 p.m.  The flyer says,

  "During the concert William McVicker will talk about the blind
  organist, Alfred Hollins, who recorded rolls for Welte, and several
  pieces will be played through the unique roll-playing mechanism.
  After the concert you will be invited to view the organ and the
  roll-playing mechanism and to ask questions.  Tickets £15.00"
