Versatile American arranger/conductor who started as a trombonist with several big bands, including Tommy Dorsey. In a long, distinguished career, he not only scored numerous films and television shows, but made many now-legendary recordings in collaboration with such people as Rosemary Clooney, Nat 'King' Cole, and, most notably, Frank Sinatra. With the latter, he recorded a series of albums now regarded as legendary ("Songs for Swingin' Lovers", "The Concert Sinatra", etc.). He recorded prolifically on his own, as well, scoring two top-ten hits with "Lisbon Antigua" (#1, 1956) and "Theme from 'Route 66'" (# 10, 1962). In his later years, he made a series of successful albums with pop diva Linda Ronstadt.
