Marshall Howard Crenshaw (born November 11, 1953) is an American musician, singer and songwriter best known for his song "Someday, Someway", a Top 40 hit in 1982.

His music has roots in classic soul music, British Invasion songcraft, Burt Bacharach and Buddy Holly -- the latter to whom Crenshaw was often compared in the early days of his career, and whom he portrayed in the 1987 film La Bamba. Crenshaw is also a noted guitarist who uses offbeat chord progressions (almost verging towards jazz) and concise solos.
