If I am not mistaken, High Lonesome has a brief clip of the original Carter family playing--or am I confusing it with a different one.

The "Times Ain't Like They Used to be" also has the boxer Jack Johnson leading a jazz band. He is the one, mentioned by Leadbelly. in "Farthewell Titanic" as trying to get on board; but being refused because he was black (or as the song goes, the captain said, "We don't hall no coal.")
