Denis Anderson asks what player-piano associations there are in the UK.
The Player Piano Group PPG) Bulletin (very informative these days) and
Membership List between them list all the UK suppliers of materials
and rolls; you join the PPG by writing to the Membership Secretary,

    Malcolm Billingsley
    80 Montalt Road
    WOODFORD GREEN
    Essex IG8 9SS  ph 0181 505 1850

The 1996 subscription price was =L=11.00.

The PPG is a jolly and sociable group who have meetings in the London
area sometimes as often as twice a month.  The main thing is enjoyment
and chat with serious seminars on particular systems or performers less
in fashion than they once were.  

The more serious side of the player and reproducer is attended to by the
Friends of the Pianola Institute (FPI), being a charitable trust with
intentions to set up an archive and demonstration rooms.  The Pianola
Institute produces an annual Pianola Journal pitched to interest inter-
national musicological libraries, so a fairly severe affair.  The latest
issue carries the first printed score of Paul Hindemith's Toccata for
Mechanical Piano, transcribed from the (red) Welte roll.  The FPI
Membership Secretary is:

    Mike Davies
    70 Blackheath Park
    Blackheath
    LONDON SE3   (I don't have phone number - he's just moved)
          
Both the PPG and FPI host high-quality recitals, sometimes jointly.  
Regional groups are:

    North West Player Piano Assocn
    % Everson Whittle
    47 Raikes Road
    PRESTON PR1 5EQ  ph 01772 792795

    The Player Piano Assocn of South Wales & The West
    % Graham Kent
    Goldtrieve
    54 Over Lane
    Almondbury
    BRISTOL BS12 4BW  (no phone number given)

Good hunting !
