Well, Jack beat me to it, but I strongly second his choice of the Jim Ringer version as the absolute best ever. Philo/Rounder put out a Best Of Jim Ringer CD last year, (Philo 1202) 17 cuts in all. It does not include Geronimo's Cadillac, however.I just checked, The Bramble And The Rose, Philo 1055, 1978, is still available, but only on cassette. (I know that Rounder has some titles still available in vinyl, so if a person prefers that, just ask them) Info, including a sound sample of Geronimo's Cadillac here~~ http://www.rounder.com/rounder/catalog/bylabel/phil/1055/1055.html
I was fortunate to be able to see Jim and Mary McCaslin (another great voice) live in St. Louis in the mid seventies. I also have all of his albums, (I think) including two with the Sweets Mill String Band.
