It s generally accepted that no actual voice recordings of Twain still
exist.
Hal Holbrook wrked out his vocal interpretation with the help of Isabel
Lyon,
one of the few people he could ask who knew his voice well.  What intrigued

cording Edison made of someone else.  This seems more possible than any
other
recording having gone unnoticed for nearly a century.
