"The Mountain of the Women" by Liam Clancy, and "Theo - An Autobiography" by Theo Bikel. Both guys were great storytellers. Especially Liam makes his childhood come very much alive.

Also enjoyed "Daybreak" by Joan Baez, "The Incompleat Folksinger" by Pete Seeger, "Bound for Glory" by Woody Guthrie, and "How can I keep from singing" by David Dunaway.
