Remember, Elvis Presley was Led Zeppelin’s greatest hero. Robert Plant explains that fact in an interview a few years back. The British public actually have more of a fascination and respect for Elvis than Americans starting in the early 60s. American kids in the 60s and 70s did not listen to Elvis, as did British kids in the 60s and 70s. Elvis was an idol of the American 50s and kept going on 60s films (sex appeal) & nostalgia performances in the 70s. He was much more influential on British artists (Beatles, Zeppelin, Stones, etc.. which in turn were much more influential on American artists. The LZ song “10 Ribs & All/“ is a Presley cover song of a Hymn he recorded. It has a similar chord progression and everything, but is a unique re-worked LZ (JPJ) song. Please note this song is created by JPJ and not Page. I know it’s Page’s band, but it would have never been LZ if it weren’t for the grossly underrated JPJ. This is his song. I’ll leave it to the reader to find out which one. As for the title, I have no idea about the “ribs” but as for the “pods” it refers to a religious poem. The song is from a hymn that Elvis recorded, although the title and various movements within the chord progression have been changed.
