It is generally considered that there were two sessions in the World Broadcasting, New York studio in February and/or March 1934.
Personnel on the first session (a):
Benny Goodman (cl), Bunny Berigan, Shirley Clay** (tp), Joe Harris** (tb), Hank Ross** (ts), Art Schutt (p), Dick McDonough (g), Artie Bernstein (b), Gene Krupa (dr), Red McKenzie (vocal).
Personnel on the second session (b):
Benny Goodman (cl), Bunny Berigan, Mannie Klein (tp), Jack Jennye (tb), Art Rollini (ts), Art Schutt (p), Dick McDonough (g), Artie Bernstein (b), Gene Krupa* (dr).
* Another body of opinion holds that Stan King or possibly Sammy Weiss replaced Krupa, Krupa's opinion was that he cut them all.
** Another body of opinion holds that Klein, Jenney and Rollini are on both sessions.
