With the pending release of "Celebration Day", no one could fault you for letting your imagination drift a bit and imagining a Zeppelin tour. In his recent interview with Rolling Stone, Jimmy Page puts any talk of that to bed straight-away. Sorry folks.
I'm too young to have had the chance to see Zeppelin live. They are one of the most influential bands for me. I started playing guitar because of Jimmy Page. Even as a bunch of doddering oldsters, I still would have paid top dollar to see them in flight one more time.
