I would like to thanks you folks here for your knoweldge and love of folk music. I've never heard about John Hartford before this thread (excuse my ignorance, but I'm little far from these great things) and now I'm listening to the album «Retrograss» (with David Grisman and Mike Seeger) - the only one availble at my record store - and I love it! I didn't know it, but that's what I was looking for!SP
