being a huge Beatles fan, not to mention zeppelin, I find it hilarious that when anyone chooses to polarise an argument theses groups,in particular the Beatles are held up as the standard against which they measure their own preference.In doing so they actually defeat their own argument, effectively raising the profile of the thing they want to denigrate.Another salient point may be relevant ie: The Beatles had a recording life-span of approx 9 years, look at the way in that period that they advanced music universally,even presenting the Stones with their first chart success along with scores of other artists who recorded Lennon & MCcartney numbers that were either never released by the Beatles or were only released on albums. Incidentally I don't agree that no-one influenced the Beatles, it's pretty well documented that Buddy Holly was a major source of inspiration that is recognisable particularly in their early work.
