Paul Clayton, Wild Mountain Thyme. Baez version from the "Farewell, Angelina" album. A snippet of the same song by Dylan and Baez with a beaming Albert Grossmann looking on. And while we're at it, here is Joan with Farewell, Angelina. Beautiful as it is, it doesn't touch the magical quality of Dylan's own version which is in a dimension by itself.
Who's Gonna Buy You Ribbons (When I'm Gone). Dylan borrowed a bit of the melody and some of the lyrics for his "Don't Think Twice, It's All Right." Here performed by Marcus Mumford and Justin Hayward-Young.
Dylan talks about Clayton in the former's Chronicles, Volume One, Simon and Shuster, 2004, pp. 260-261.
Mark Spoelstra is also discussed by Dylan somewhere in Chronicles. While I flip through the pages, you enjoy Sugar Babe, It's All Over Now. The title puts me in mind of Dylan's wonderful It's All Over Now, Baby Blue. Bonnie Raitt does a good job with it. Or perhaps you prefer the angel-throated Joan Baez. Comparing these two songs one sees why Spoelstra, competent as he is, is a forgotten folkie while Dylan is the "bard of our generation" to quote the ultra conservative Lawrence Auster.
Ah yes, Spoelstra is mentioned on pp. 74-75.
About Karen Dalton, Dylan has this to say (Chronicles, p. 12):
My favorite singer in the place [Cafe Wha?, Greenwich Village] was Karen Dalton. She was a tall white blues singer and guitar player, funky, lanky and sultry. I'd actually met her before, run across her the previous summer outside of Denver in a mountain pass town in a folk club. Karen had a voice like Billie Holliday's and played the guitar like Jimmy Reed and went all the way with it. I sang with her a couple of times.
