Input: Question: Which of the musicians that Wright played with in a trio for Jack Berch's NBC show had the longest career? Passage:In 1938, he had his first playing job at a Chinese night club in Oakland, called the New Shanghai Cafe and Terrace Bowl, which boasted a 2-manual, 6-rank Wurlitzer; the show was broadcast nightly by an Oakland radio station. In 1941, he joined San Francisco radio station KFRC and on the Blue Network by 1942. In December, 1942 he started performing at the San Francisco Fox Theater on Saturday nights. In late 1944, he relocated to New York City to work as organist for NBC radio. He began recording at this time, first cutting 78 RPM records for Syd Nathan's King Records and Regent Records, in addition to securing contracts for transcription disks on the Thesaurus, Associated, and Muzak labels. In New York, he was a guest on the Paul Whiteman"Stairway to the Stars" radio program (May 21, 1946) and Percy Faith, as well as on the network shows of Bing Crosby and Perry Como. He also conducted his own orchestra on the Robert Q. Lewis show and began a seven-year stint playing in a trio with Charles Magnante, accordionist, and Tony Mottola, guitarist, for Jack Berch's NBC show sponsored by the Prudential Insurance Company. The trio, with added bassist Bobby Haggart, recorded five "Soundies," as well.
