conduct a Victor recording with Dorsey and Jose Iturbi. Shortly before the planned recording date, Dorsey signed a contract with Decca, and a recording at the Victor studio was not possible. Shilkret recorded an arrangement for trombone, piano and chamber orchestra in November 1947, with trombone solo by Will Bradley (Wilbur Schwitchtenberg) and piano solo by Leonard Pennario. The recording had a limited pressing as Aztec 248 (Aztec was a label belonging to Nathaniel Shilkret Music Company, which was owned by Shilkret's son Arthur), but the recording was never issued commercially. In 1944 Shilkret and Phil Moore wrote a dance arrangement of the third movement of the concerto entitled "Specie Americano." This was recorded as one of the first pressings of the Discovery label. It was released in 1948 as Discovery 1200 (a twelve-inch 78 rpm) with the title "Concerto for Trombone--Parts 1 and 2," recorded by the Phil Moore Orchestra, with Murray McEachern as trombone soloist. The liner notes to the recording say that the dance arrangement was "first performed 1946 by Paul Barron with the CBS Symphony Orchestra. Soloist Will Bradley." Shilkret wrote "The Crazy Cool Musician in Between," with lyrics by Art Sydney, as a popular song based on the third movement of the concerto. Barbara Shilkret, daughter-in-law of Nathaniel Shilkret and owner of Nathaniel Shilkret Music Company from 1982 to 2004, claimed a 45 rpm recording by artist Phil Leeds was made of the song on the Aztec label. No such recording has ever been found in the Shilkret archives. However, a July 21, 1953, air check of the female vocal group, the Metrotones, singing the song on WHAS-AM (CBS) is in the Shilkret archives. WHAS was the Louisville, KY radio station with which Art Sydney was affiliated. An August 19, 1954, press release announced, "WNBC concert Sunday, August 29, 1954, directed by [Le]Roy Shield, will play the first radio performance of Maria del Carmen (Granados) and Concerto for Trombone and Orchestra by Nathaniel Shilkret, with Neal di Biase, formerly first trombonist with the NBC Symphony, as soloist.” Granados biographer Walter A. Clark confirms that the concert was broadcast. Shilkret was a guest on the July 3, 1956, broadcast of The Classical Disc Jockey, hosted by Tom Baxter, on the Los Angeles radio station KABC AM/FM, and the broadcast ended with an excerpt of the third movement of the concerto.
