I've searched for this online, but no hits worth anything. Am I really the first person to document the striking similarity between Jerry Lordan's 'Apache', a big hit for the Shadows in 1960 which has since become something of a legendary recording, and Philip Glass' 'Metamorphosis #3', apparently 'composed' in 1988?
