Thanks to Mr. Bochynski for supplying a great interview for us Twainians!

Several weeks ago I spoke with the owner of the guitar, Hank Risan, for
about 15 minutes.  He asked me to write to him, and I have just finished my
letter which includes a question  regarding the precise source of the poem,
"Genius".  I will post the answer to that question, and also supply more
information regarding the claims of provenance as soon as I get this

Twainiacally Yours,  Bob  Slotta
