Led Zeppelin charged with copyright infringement

From Led Zeppelin being sued by suriving member of Spirit over 'Stairway to Heaven' , one sees an assertion that the opening notes of 'Stairway to Heaven' were copied without permission by guitarist Jimmy Page :


The suit is being brought by the founding bassist [ Mark Andes] of Spirit, an obscure 1960s band that Led Zeppelin toured the U.S. with back in 1968 and 1969.



BUT


Mick Wall wrote in 'When Giants Walked the Earth: A Biography of Led Zeppelin,' what Jimmy Page did 'was the equivalent of taking the wood from a garden shed and building it into a cathedral.'
