David Mansfield (born September 13, 1956) is an American musician and composer. 　　Raised in Leonia, New Jersey, his first band was Quacky Duck and His Barnyard Friends, which also included two sons of Tony Bennett. 　　Bob Dylan asked Mansfield to tour with him on his 1975 Rolling Thunder Revue tour; he remained in Dylan's band through their 1978 world tour. 　　After the Revue ended in 1976, Mansfield and two other members of Dylan's band, T-Bone Burnett and Steven Soles, formed The Alpha Band. The band released three albums, The Alpha Band in 1977, Spark in the Dark in 1977, and The Statue Makers of Hollywood in 1978. While Mansfield in 1978 was working on the album, The Statue Makers of Hollywood with The Alpha Band, he appeared as a guitarist on Desire Wire (Cindy Bullens album) by a struggling pop/rock artist Cindy Bullens that same year.
