Procol Harum and co-writer of the iconic 1960s hit “Whiter Shade of Pale,” died on March 23 after a battle with cancer, according to a post on the band’s website. He was 76. Reid’s acclaim with Procol Harum — from its eponymously-titled 1967 debut album until 2003’s “The Well’s on Fire” — came from his unusual turns of phrase and influences from classical literature on songs such as “A Salty Dog,” “Conquistador,” and most famously “A Whiter Shade of Pale,” an unusually lengthy and unlikely hit that has gone on to become one of the most commercially successful songs in history.
