Christy Moore has written something which is autobiographical,
if not exactly an autobiography. It has the lyrics to a couple hundred
of his favorite songs, and for each song there's a page which talks
about the song, or how he & the song met, or some incident in
his life that has some bearing on the song - if you put it all together
you learn a lot about Moore's life, just not in the orderly way that
you would in an actual biography.

On the American side, I've read biographies of Leadbelly, Woody
Guthrie, Lee Hays, Pete Seeger, and autobiographical works by
Judy Collins & Joan Baez.
