Chick Webb fired a saxophonist with this first name from his orchestra for trying to convince Ella Fitzgerald to join his band, which became the Tympany Five. That jump blues bandleader with this first name sang hits like “Choo Choo Ch’Boogie” and “Is You Is or Is You Ain’t (My Baby),” and has the surname Jordan. A bandleader with this first name holds a high B-flat for four measures on a 1928 track that opens with a 15-second (*) trumpet cadenza. A musician with this first name trades off with Earl Hines’s piano on “Weather Bird,” a song composed by his mentor “King” Oliver. That musician recorded “West End Blues” with his Hot Five, and sang the (-5[1])title song of “Hello, Dolly!” in his trademark (10[1])gravelly voice. For (10[1])10 points, give this first name of the trumpeter who sang “What a Wonderful (10[1])World.” ■END■
