Serendipity. I'm wearing a Led Zeppelin T-Shirt today that my son gave me. You're not alone living in the past, even if I don't spend all my time there. :-)
I think the comments with people listing their favorites that should have made your list. That I think just proves your point about how great they were. Everyone has some different favorites, but no one stopped by to hate post what a shit bad Zep was.
I've probably commented this before, but I just missed my chance to see them live. I was old enough to have a job and my friends and I were planning to buy tickets when Bonham died and it all ended.
I respect Robert Plant for never going back for more than a gig. He lost a child, a marriage, and then his best friend who he started in the band with. Going on or going back would have brought a steamer trunk of baggage with it.
