John Patrick Boylan IV, is an American record producer and songwriter.
Upon graduating from Bard College, he and his brother Terence worked with music publisher Charles Koppelman before moving to Los Angeles in the late 1960s. There they recorded an album as the Appletree Theatre. After a stint as one - third of the group Hamilton Streetcar which in 1969 recorded a self - titled album for Dot Records, John then started to develop a career as a producer, working with Ricky Nelson, the Association, the Dillards and others. He also managed Linda Ronstadt in particular introducing her to a then unknown group of musicians who went on to become her backing band in 1971, and later became the Eagles.
After working in the early 1970s with Pure Prairie League and Commander Cody, he had one of his biggest successes sharing the production duties of the first Boston album with the band's founder Tom Scholz. The group's label, Epic Records, rewarded him by offering him the position of Vice President, West Coast, where he stayed for a decade. During this period, he produced many further successful albums, notably with Charlie Daniels, Mickey Gilley and the Little River Band. In 1986, he left to form his own company, Great Eastern Music. One of his first projects was to produce the highly successful album The Simpsons Sing the Blues.
