Here are the two versions, almost 40 years apart.Out of the swirling ocean of psychedelia, which included Jefferson Airplane's 'Somebody to Love' (a Top Ten hit in May) and The Doors' 'Light My Fire' (June's #1 hit) there had arisen a dark and mighty leviathan with a strange and magical name: PROCOL HARUM. The name, misspelled from the Latin, translates as 'Beyond These Things.' The original owner of that name was somebody's cat. And like a cat, fame nuzzled up warmly and then abruptly walked away. Inscrutably, critics trashed the golden band's follow-up single 'Homburg' for either being, or not being 'A Whiter Shade of Pale.' Management and personnel problems added to the bad luck. Other bands made a big splash and didn't repeat. Jefferson Airplane, to cite one example, disappeared from the charts completely after 1967's 'Somebody to Love' and 'White Rabbit.' But 'A Whiter Shade of Pale' was THE hit of 1967 and it burdened the band with a legend they couldn't live up to.
I also had quite a fondess for Simple Sister, and of course, Conquistador!
