"A Whiter Shade" of Pale was the first single by Procol Harum (1967) and was one of the greatest hits of the psychedelic era. Gary Brooker created the melody, but the iconic, baroque organ riff was improvised by Matthew Fisher (inspired by Bach). The track mixes rock, classic and psychedelia in a way that no one had done before. It became #1 in the UK for 6 weeks and sold over 10 million copies worldwide. Years later (2006/2009), Fisher sued the band and won copyright for the organ riff he created.
