I arranged Leroy Anderson's "Typewriter" a few years ago for Alderman
26er scale and have performed it a few times, with a separate bell
connected to one key.  Some people know the piece and like it; many
(here in Europe) don't know it, then it's just some curiosity.

Usually I had some organ-grinding friend to turn the crank.  At one
time one from the audience did it, and it worked nicely!

Learning to type fast enough without clogging the type bars took me
a few days of training, and my success rate performing it without an
accident along the way is still below 50 percent, I confess...
