Good post, PG. A lot of what I learned in the alternating bass style when I was starting out was from two Happy Traum books called, I believe, Fingerstyle Guitar. They started you out with fairly easy tunes like Freight Train, Railroad Bill, Bully of the Town, Creole Belle, etc. and increased in difficulty from there. Traum, course is the founder of Homespun Tapes and has put together all kinds of lessons for players at all levels.vl
