"Didn't He Ramble" (also referred to as "Oh! Didn't He Ramble") was composed by J. Rosamond Johnson, James Weldon Johnson, and Bob Cole in 1902. This was used by New Orleans jazz bands from the early 20th century on. It was recorded by Charlie Poole and the North Carolina Ramblers. I learned it from Charlie Poole and the North Carolina Ramblers
