He could definitely play the guitar.
I wonder if Lester Flatt or Earl Scruggs ever recorded something like that?
Not to my knowledge. Tommy Emmanuel does Yankee Doodle and Dixie simultaneously - perhaps learned from Chet Atkins - which might be good music for the fourth, but I don’t know of a good clean recording of it. Just didn’t want to go too far down the rabbit hole looking. Simon & Garfunkel’s Central Park " American Tune" might have a place also…
