Hey, Bob, are you sure you're not mis-reading the date? Walt Robertson attended Haverford College (which is right down the road from Swarthmore) in the late Forties, and he took in all the Swarthmore Folk Festivals while he was there. I know he met Richard Dyer-Bennet, John Jacob Niles, Woody Guthrie, Pete Seeger, the Lomaxes, and God knows who all else. Leadbelly sang there in 1946. Walt could have met him then.Don Firth
