"Rehearsing for a 1976 Whiteman commemorative concert under [Dick Sudhalter's] leadership, saxophonists Al Gallodoro (a Whiteman alumnus), Johnny Mince (soloist with Tommy Dorsey's 1930s orchestra), and Eddie Barefield (star of the Cab Calloway and Chick Webb bands) astonished fellow-bandsmen by reeling off the chorus from memory, in faultless unison. "Why, of course everybody picked up on that one," was Barefield's explanation..."
ibid., Ch. 15, p. 368:
"'Everybody listened to [Jimmy Dorsey] and Trumbauer,' saxophonist Eddie Barefield declared. 'We wrote out his 'Tiger Rag' solo from the Whiteman record in four-part harmony and played it that way. He was just as much admired by black musicians as by white; though a lot of black musicians went for Trumbauer because of his style, Jimmy was in some ways just as good.'"
The Whiteman record, by the way, is an ambitious retooling of the old ODJB standard "Sensation Stomp" penned by Don Redman for Whiteman. The band modulates into the "Tiger Rag" chord changes only for the duration of Jimmy Dorsey's solo, then it is right back into "Sensation."
