The song transition Bonnie was referring to was Nick Lucas's "Pickin' The Guitar" to Sam McGee's "Buckdancer's Choice" to Doc Watson's "Doc's Guitar" to my "Rag Eh?"Since there is already a thread on Leadbelly's "Good Night Irene", I did a similar thing with his treatment of Sam Kennedy's Irish "cow" ballad and how it evolved (with Lee Hays' help) into "Kisses Sweeter Than Wine".
