John Boylan (record producer)

John Patrick Boylan IV (born March 21, 1941, New York City), 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 (with Buzz Clifford of "Baby Sitttin' Boogie" fame, and original group member Ralph Plummer -- the group was originally named on behalf of former member John Burge, aka Ian Hamilton) which in 1969 recorded a self - titled album for Dot Records (Dot: DLP25939), 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.
