Greatest Hits is a compilation album by the progressive rock band the Moody Blues, released in 1989. The band recorded new versions of "Isn't Life Strange" and "Question" with orchestration by the London Symphony Orchestra. The arrangements were overseen by Anne Dudley, who also produced the recordings with Justin Hayward and John Lodge. The album was re-released as The Story of the Moody Blues – Legend of a Band in 1990 to coincide with the release of the documentary of the same name.
