Speaking of Mike Longworth (see first post in this thread), there is one picture of Mike in my photos collection at http://rudegnu.com/art_thieme.html

It was taken back stage at the grand Walnut Valley Festival in Winfield, Kansas. Mike would never forgive me for altering my Martin D-76 guitar--the one I won in a raffle at Chicago's Old Town School of Folk Music. I turned it into a 9-string guitar by putting 3 planetary banjo gears down the middle of the tuning stock.
