In the Pete Seeger Banjo Vituosity thread Rick Fielding made this statement.

A great transitional player was Bill Keith who transcribed Scruggs Playing in the sixties, A LOT of Northerners got the style from that. This incredible book almost didn't happen.....Louise's lawyers had to settle a lawsuit on the courthouse steps, rewarding Keith for all the work he'd put into it! Glad they did!

Rick, can you give us more details?
