John,

For Ken's book, try Elderly Instruments. There is more information at Amazon.com. There is an accompanying instructional video as well, but I must warn you I've been having quality problems with the video. (Centerstream exchanged my first one very nicely, but the second one is also screwed up.) There also seem to be two versions of the video--the original that only covers the first half of the book, and another with the rest of the songs added in a recording made several years later.

The Steve James book I mentioned that I've started using as a repertoire book is also at Elderly and Amazon. The author has a video with a subset of the songs in the book.

Hope that makes it easy. :-)
