Has it ever been substantiated (or disproved) that it was Bix who was the cornetist on this Benny Goodman recording date? (Also from this session: "Deep Harlem" and "Strut Miss Lizzie".) Rust says Bix was present. Lord's and Connor added the proviso "...no one can state with certainty the identity of the cornetist on this session". Has more information surfaced in the last 25 years or so? I did a search of the Forum archives and didn't see much relating to this.
