In 2005, Brian Clarke designed the cover for Fine Line, a single by Paul McCartney from the album Chaos and Creation in the Backyard, released on 29 August 2005 in the UK as the album’s lead single. The cover design is based on a silhouette of McCartney's hand and draws on a series of studies and photographs Clarke made of the musician’s hands in motion and while playing.

Other collaborations on album covers for Paul McCarteny include the design for Tug of War, Figure of Eight and Flowers in the Dirt.
