During the 20s Brunswick years (4000 serie), Ellington's orchestra was aliased The Jungle Band for a handful of cuts.
Later on, Brunswick reissued these in the 6000 serie under Duke Ellington & his Orchestra.
Though, they incorrectly attributed Brunswick 4450 to Ellington (reissued as Brunswick 6808 - Dog Bottom / Jungle Mama) - while it's indeed from another Jungle Band, actually the first record of Chick Webb and his formation.
This error persisted and is still present in some modern reissues.
If you happen to find Dog Bottom and/or Jungle Mama in recent Ellington reissues, they are likely not from the Duke, but from the King of the Savoy.
