On the "Bring It On Home" issue -- a couple of corrections. First, the song was not written by Williamson, but by Willie Dixon, who is credited properly on every Chess release of the song I've seen, which includes the various Williamson versions (in addition to the Matt Murphy/SBW version, there are at least two Chess single sides from the 50s on which Dixon plays bass) and also a version by Walter Horton from the early sixties (which Dixon sings on).
Zeppelin stole many, many blues songs, and the only reason this song was EVER properly credited was because Dixon went to a great deal of expense and trouble to sue them and drag them through court. He had to do it twice, because "Whole Lotta Love" is also stolen from one of his songs.
Most of the other blues (and some rock&roll) singers that Zep raped, ranging from Robert Johnson to Ritchie Valens, never received any recognition or money from the band.
Compared to the way the Rolling Stones always credited/talked about their blues influences, and the way Eric Clapton has always approached his musical ancestors, Zeppelin's behavior was arrogant, piggish, and just plain wrong.
