Wesley, Fisher himself acknowledged his debt to the Bach piece.

Melodeonboy and Fat Bastard: Most of the royalty income to be earned from Whiter Shade of Pale has already come in. Fisher lost his claim for backdating his entitlement to a share in those royalties. He also had to meet his own legal costs in the case, which came to about £500,000. Cynicism is a predictable reaction to any case involving big numbers, but I think you can rest easy in the knowledge that Fisher won't make much money out of this one.

If I'd made the kind of contribution to a song's success that Fisher did, I'd want my name attached.

By the way, wasn't it a spat over the credits for House of the Rising Sun that drove a wedge between Eric Burdon and Alan Price?
