Permission to appeal was granted on the basis of (1) the unusual length of time that had elapsed in making the claim (2) the insistence of the defeated defendants of the widespread and dire effect that the decision would have on the way that the music industry operated in the past.
In 1967 Gary Brooker composed the music of "A Whiter Shade of Pale" around lyrics written by Keith Reid. The dispute is about the authorship of the arrangement of the song. In the course of rehearsals improvised changes were made to the song: the words were shortened from 4 verses to 2 and the instrumental sections were all played by Matthew Fisher on the Hammond Organ. The single issued on May 12th 1967 was a recording of a performance by the band. In August 1969 Matthew Fisher left Procol Harum. The band's partnership was dissolved with the understanding that Fisher would not be liable for the band's debts of $60, 000. He signed a release but not with respect to a share of copyright or publishing royalties for his compositions.
Blackburn J. found in the High Court that "Mr. Fisher's instrumental introduction (i.e. the organ solo as heard in the first eight bars of the Work and as repeated) is sufficiently different from what Mr. Brooker composed on the piano to qualify in law, and by a wide margin, as an original contribution to the Work".
On appeal it was found that the judge was entitled to find that Matthew Fisher made a creative contribution to the Work and he was right to grant a declaration as to co-authorship. This decision therefore stood. He however dismissed the appeal on the joint ownership of the musical copyright and the finding that the implied licence to exploint the work had been revoked when Matthew Fisher filed his action. Lord Justice Mummery found that Matthew Fisher was guilty of "excessive and inexcusable delay" and that his acquiesence made it "unconscionable and inequitable" for him to seek to control commercial exploitation of the work after 38 years. No damages were awarded and no right to exploit the work in the future was granted.
