These songs (as well as the picture of Gillian Welch) were taken down after I was served with a DMCA notice. It seems strange to me that Ms. Welch (and/or her emissaries) would find their inclusion detrimental, rather than beneficial, to her overall career, but there it is. Don't worry, Gill, I still love your music!
In honor of this great show, I dug up three Welch/Rawlings covers: "White Rabbit," Paul Simon's "Gone at Last" (originally a duet with the recently departed Phoebe Snow), and Bob Dylan's haunting "Oh, Sister" from 1976's Desire.
P.S. If you dig Gill but aren't familiar with Crooked Still and singer Aoife O'Donovan, check out my recent post Aoife Sings Simon and the Stones; you'll be a convert.
