I would just like to thank the readers of the MMD who took the
trouble to contact me after my appeal published in the MMD of 17.12.12.
Not only did I learn the likely identity of the one-armed pianist but
have been enabled to find a way to rotate the pages and, as a bonus,
to learn about another fascinating book about the Hupfeld Company:
"Im Aufnahmesalon Hupfeld" [Verlag Janos Stekovics, Halle an der Saale,
ISBN 3-932863-34-8].

I was certain that the MMD members would be able to help.  Thanks again
and season's greetings to you all.

Jon Polden - from a now unseasonably warm UK, where a white Christmas
is now just a dream!
