The unprecedented success of “Star Wars” propelled the western to outer space. What is little known is that “Star Wars” composer John Williams, like many of his contemporaries, scored a number of actual, old school westerns. Join Ross Amico for a Williams’ western round-up, including music from “The Cowboys,” “The Man Who Loved Cat Dancing,” “The Missouri Breaks,” and “The Rare Breed,” this Friday at 6 pm.
