When Cab Calloway threw Dizzy Gillespie out of his band for supposedly playing "Chinese music" during his solos, Collins was the subsequent replacement. The bebop quotient must have been more satisfying to the leader, as the trumpeter kept this job until 1943, then rejoined the Calloway show from 1944 through 1946. In the late '40s and early '50s, Collins performed with Buster Harding, Al Sears, and Jimmy Rushing, the latter leader helping to bring more of a rhythm & blues feeling to Collins' riffing. With many big bands folding, this turned out to be a good development in terms of employment. The funky tenor saxophonist Sam The Man Taylor was Collins' main employer throughout the '50s and even into the '60s, when the trumpeter began gigging on more of a part-time basis. Collins was an active composer and arranger whose creations include the frequently recorded Rock-a-Bye Basie. ~ Eugene Chadbourne, Rovi
