well you lost me at peter grant comment actually for I am a felon....
as far as forgetting his words heroin will do that to ya, Robert often changed the song not necessarily forgot the lyrics.
when John Bonham died the broke up....most bands if not all, continued.
they did nothing that other artists haven't been always doing....period. they changed every thing they used or borrowed and made it there own.
as far as Led Zeppelin being a studio band only.....well You could not be further from the truth sorry major FAIL...Led Zeppelin has been called the greatest live rock band by to many people to have sucked, I also know people that have seen them live....I started listening to them in 1979,
that is so laughable wow.....besides the fact ive had at least 40 live albums and tapes/CD's to 8tracks. watched countless videos of them....
They were great live.
the whole of your post screams envy sorry, you have eluded to this before...glad you finally got it off your chest 
As for my Felon comment it was true. He had the "hoax robbery after the MSG gig"..........you draw your own conclusion.
I'm not envious, I've read a few books and left out other things, but why bother? "FAIL"? Are we adults here, or are some of you kids sitting around the breakfast table? Don't know how I lost you, as you called Peter Grant.........Peter Green more than once.
I may be 37 ink, but I assure you that I've been listening to them since about 4 years old and it's far from envy. I have the bootlegs, seen a lot of the videos as well, some things are just fact. The older I get, the more I'd rather listen to Willie Dixon, Leadbelly and the influential artists "that get ignored".
