Apropos of nothing, I love this picture of Jelly Roll Morton, evidently lecturing the members of his Red Hot Peppers.
This was 1926 or ’27 in Chicago. Behind Morton from left to right are Omer Simeon, clarinet; Andrew Hilaire, drums; John Lindsay, bass; Johnny St. Cyr, banjo; Kid Ory, trombone; and George Mitchell, trumpet. To hear them play “Grandpa’s Spells”, click here.
