Well I have a Harmony uke that my father played, and it's possible that Arthur Godfrey (or even Tiny Tim for that matter) MAY have touched it. After all they both lived in the U.S. and may have had occasion to visit an insurance salesman. Now that I think about it, Harry Truman or Richard Nixon may also have played it. Well it's possible anyway.
I think I'll start with a reserve of merely 5000 dollars. If anyone's interested, I'll keep thinking of famous people who MIGHT have played it. Like Mother Theresa in her Hawaiian period.
