Alfonso D'Artega (June 5, 1907 – January 20, 1998), often known simply as D'Artega, was a songwriter, conductor, arranger and actor. His song "In the Blue of Evening", co-written with Tom Adair, was a number one hit for the Tommy Dorsey Orchestra in 1943. D'Artega wrote over 50 songs. Perhaps his most widely recognized composition in the U.S. is "The NBC Chimes Theme".
