Hi!  Going over old postings, I am very surprised to see that no one
replied to this posting thread [080729 MMDigest], at least according
to the Archives.  There is a firm making a go of it, doing exactly this
to Glenn Gould performances (Glenn had a squeaking chair and hummed
during his performances, to start).  See http://www.zenphstudios.com for
more information.

Good luck,
Jim Cook
