The mistake is only the date, but it is a bonus, as said in the notes. "As a bonus, we have managed to secure a recording of the encore Dixie, by Daniel Decatur Emmett, which Toscanini performed in Atlanta, Philadelphia and, as heard here to an astonished and rapturous reception, in Richmond,
Virginia, earlier in the tour. The music librarian to the NBC orchestra at the time, James Dolan, introduces the piece
with a fascinating account of how it came to be included in the Maestro's programme."
