I just thought of something.George Ward, MC at the Fri night concert sang John Hartford's "Old Time Riverman" as a tribute to John. He told me he sang it as a direct result of Catspaw telling him about it on a thread here. He said somebody ought to let folks at Mudcat know he did it, and why he did it. On behalf of George, thanks for the song, Spaw.
