Classics classic rock October 17

Many classic rock songs have been based on.well..the classics. Because by The Beatles was based on Beethovens Moonlight Sonata played backwards. In the sixties The Toys had a hit with Lovers Concerto which was Bach's Five Finger Piano Exercise, Beck's Bolero was based on Ravel's Bolero, Eric Carmen lifted I'll Never Fall In Love Again from a Rachmaninoff melody...Frank Zappa, Emerson Lake and Palmer, Dave Edmunds and others all lifted classical riffs. Perhaps the most well known classic inspired song was the 1967 number one hit A Whiter Shade of Pale from Procol Harum..it was based on the Bach Contata Sleepers Awake...it was so popular that more than 800 recorded cover versions are known. The original organ riff was played by Matthew Fisher who 39 years after the fact took Procol Harem to court claiming that he had written the piece and he deserved a writing credit...ignoring the fact that Bach deserved more credit the court awarded Matthew 40% of the copyright value and future royalties...6 months ago an appeals decision reversed the earlier outcome..still no credit for Bach though..
