Fisher v Brooker [2009] FSR 25, HL
Mr Fisher wrote the distinctive organ part in the famous song 'A White Shade of Pale' recorded by Procul Harum. The part had originally been written for the piano but had been considerably reworked by Mr Fisher. Over 30 years later, Mr Fisher claimed joint ownership of the song.
Joint authorship may result from reworking an existing work by a person if his input can be regarded as an original contribution to the work. Mr Fisher was entitled to a 40% share in the copyright but could not claim back royalties since his silence prior to making his claim gave rise to a gratuitous licence.
