Former Led Zeppelin frontman Robert Plant has dismissed rumours that the metal legends will ever play together again once and for all.Speaking to US magazine Rolling Stone, Plant said that even though the band's one off reunion show at London's O2 Arena in December 2007 was "was an amazing evening and represented all that we were trying to capture," he can no longer relate to the band's music."I've gone so far somewhere else that I almost can't relate to it," he explained. "It's a bit of a pain in the pisser to be honest." Plant jokingly added that he'll be too old to rock in the very near future:"I know people care, but think about it from my angle - soon, I'm going to need help crossing the street."
