Background: Paul Weston (born Paul Wetstein, March 12, 1912 - September 20, 1996) was an American pianist, arranger, composer, and conductor who worked in music and television from the 1930s to the 1970s, pioneering mood music and becoming known as "the Father of Mood Music". His compositions include popular music songs such as "I Should Care", "Day by Day", and "Shrimp Boats". He also wrote classical pieces, including "Crescent City Suite" and religious music, authoring several hymns and masses. Born Paul Wetstein in Springfield, Massachusetts, Weston had a keen interest in music from an early age and learned to play the piano.
Context: Weston was born Paul Wetstein in Springfield, Massachusetts, to Paul Wetstein, a teacher, and Anna "Annie" Grady. The family moved to Pittsfield when Weston was two, and he spent his formative years in the town. His parents were both interested in music, and when Paul Sr taught at a private girls' school, he was allowed to bring the school's gramophone home over the Christmas holidays. Weston remembered hearing "Whispering Hope" on it as a child. At age eight, he started piano lessons. He was an economics major at Dartmouth College in New Hampshire, where he graduated cum laude and Phi Beta Kappa in 1933. During his college days, Weston had his own band called "the Green Serenaders"; this allowed him to pay his own college tuition. Weston also learned how to play the clarinet so he could travel with the college band. He went to graduate school at Columbia University and was active in the Blue Lions, Columbia's dance band. In January 1934, Weston was seriously injured in a train accident. While trying to catch a train, Weston grabbed a door handle as the train sped off. He was able to hold on to the handle and was dragged two and one half miles before losing his grip. Unable to be active in a band, he started doing music arranging as a way to keep some involvement with music while convalescing. When he returned to New York in the fall of 1934, he made his first sale of his work to Joe Haymes. Haymes liked Weston's work enough to ask him to do more arrangements for his band. His medley of Anything Goes songs was heard by Rudy Vallee, who contacted him and offered Weston a job as an arranger for his Fleischmann's Hour on radio. Weston was also doing arranging for Phil Harris. He met Tommy Dorsey through his work with Joe Haymes. Following the Dorsey Brothers split in 1935, Tommy had yet to form an orchestra; he used the Joe Haymes Orchestra for his first engagement as a solo conductor. Weston joined Dorsey as chief arranger in 1936, holding the position until 1940. He became Dinah Shore's arranger/conductor and worked freelance for the Bob Crosby Orchestra. Weston also worked with Fibber McGee and Molly and Paul Whiteman. When Bob Crosby's band was hired for his brother Bing's film, Holiday Inn, this took him to Hollywood and into film work. He changed his name from Wetstein to Weston after his arrival in California. Weston was asked to do more work for Bing Crosby and Bob Hope, and also for Betty Hutton. Subsequent films as musical director include Belle of the Yukon (1944) and Road To Utopia (1945). CANNOTANSWER
