Three of the Caedmon albums were re-released by Rounder in the Alan Lomax series - Songs of Seduction and the 2 Child Ballad volumes. With extra tracks, but still with the annoying missing verses feature. Those CDs are probably not even available now, but perhaps can be downloaded. It's a pity the other 7 volumes were not reissued, but I understand that Peter Kennedy was the problem! He was editing them.
