Speaking of Chet Atkins and Mark Knopfler, I have a tape of the two of them together, and it's so great ... kind of half-country, half-jazz (Chet was a monster jazz guitarist, and Knopfler is just plain brilliant), and all fun -- lots of chit-chat back-and-forth joking during singing. They had a blast recording together, you could tell.
A very good history and read of Buck is at the above link..... some 27 sections..
