WHat is music if it is not the bringing together of past and present. Copyright laws were not so stringent in the 70's, and by incorporating these musicians work, which they oviously had to have known they were doing, they have allowed their work to get more publicity, adn exposure had they not otherwise done so. Jimmy Page is a genius, Led Zep performed these song that were origionally done by one guy on a porch, adn made them orchestral. to call them theif and unoriogional is laughable
