Stairway to Heaven by Richard Cole - this is basically the diary (or at least a very subjective retelling) of life on the road with Led Zeppelin by their primary tour manager, Richard Cole. It is mostly filled with stories of life on tour, including all the crazy stories that surround the band. Yes, the shark story is there in full detail. It's a interesting read in that it does reveal some character traits of the band members that may not be as readily obvious through their music and interviews. Since he was their tour manager, there isn't much about their studio time and the development of the songs and albums, which is what I would consider the most important aspect of their legacy as a band, although their touring is probably what made them most famous. This is mostly for the real fans of the band, but it is told by someone who was truly on the inside so it gives details you won't find anywhere else. I also recently re-read "Hammer of the Gods" which treads much the same ground as Stairway to Heaven
