Jim Horn is an American saxophonist and woodwind player. He was born in Los Angeles, and after replacing saxophonist Steve Douglas in 1959, he toured with member Duane Eddy for five years, playing sax and flute on the road, and in the recording studio. Along with Bobby Keys and Jim Price he became one of the most in-demand horn session players of the 1970s and 1980s.
Horn played on solo albums by three members of the Beatles, and worked on a session with Paul McCartney, who was producing a track for Duane Eddy's 1987 album project. Jim Horn also toured with John Denver on and off from late 1978 to early 1993. He also played with Denver in concert occasionally before and after the 1995 wildlife concert.
