I would have never guessed, but Louis Armstrong was a guest on the Johnny Cash Show. This and the story about Satchmo and Jimmie Rogers show how diverse musical tastes these men had and once again that music is a great connector.
This is from episode 38, Oct., 28, 1970 and must be one of Satchmo's last performances. He was such a great performer right to the end and the Nashville audience and Johnny just loved him.
Louis Armstrong cracks everybody up at the start of the song: Let's give it to 'em in black and white.
THIS AND OTHER GREAT PERFORMANCES ARE NOW AVAILABLE ON A 2-DVD-SET "BEST OF THE JOHNNY CASH TV SHOW". HIGHLY RECOMMENDABLE!
