Cornelius began performing in the '30s in ensembles led by Les Brown, Frank Dailey and Buddy Rogers. In the spring of 1939 he joined the Goodman organization which at that time had a star attraction in dynamic drummer Gene Krupa. When Krupa formed his own band in the fall of that year, Cornelius went with him, irritating Goodman. It meant joining forces with hot players such as trumpeter Shorty Sherok and saxophonist Sam Donahue but more importantly meeting singer Irene Daye. Performing on hit records including Drum Boogie and Drummin' Man, Daye became one of the most popular singers in the country. In the early '40s Cornelius left Krupa to join the the Casa Loma Orchestra followed in the pop of a cork by Daye, who became the trumpeter's bride. The singer temporarily quit performing in 1943 to raise their daughter, but returned to the microphone with even greater successful following his death later that year. ~ Eugene Chadbourne, Rovi
