Plot synopsis: Musical comedy stars of the past and present bridge the musical generation gap as they perform their particular specialties and re-create some memorable moments in show business. Highlights include Broadway's two great "Dollies", Pearl Bailey and Carol Channing, performing the top songs from "Hello Dolly!"; Patti Andrews of the Andrews Sisters joining the Pointer Sisters in the runaway hit of 1937, "Bei Mir Bist Du Schon"; the musical blending of the Mills Brothers and the Jackson Five.
