I digitized it for a friend some years ago and will put you in touch with
them offlist (since I'm not sure they'd want to be publicly identified and
burdened with numerous requests for copies). Also, there are copyright
uncertainties. Neither of us if sure if sound recordings are protected by
the same term as books (75 years), and there is the added complication that
the recording may date as early as 1920 or as late as 1935. But it would be
great if it could be made widely available, at least in this Forum. After
all, Clara's endorsement of Hal Holbrook (no disrespect to his wonderful
performances intended) was by an elderly lady who had, to put it nicely,
lost her focus on reality, and she had not heard her father's voice in
nearly fifty years (moments after she pronounced his impersonation of Twain
dead-on she told him he should impersonate Jesus). But Twain himself, while
still focused and with no thoughts of Jesus to get things crosswise, thought
Gillette nailed him (Twain, not Jesus)..
