Shellac Stack No. 168 jumps with Cab Calloway, parades with Paul Whiteman, and cakewalks with Hazel Gertrude Kinscella. We hear records by the Korn Kobblers, Ben Berlin, Nat Shilkret, Ted Weems, Leroy Montesanto, Olive Kline, and even a full-length “Junior Operetta” from c. 1923 in this musical children’s hour.
