John Bonham died before I got to see LZ - but I did see Robert Plant in concert several times. I went to so many concerts in the 80's - Boston, Billy Squire, Def Leppard, Yes, Peter Gabriel, Rush, Ozzy, The Who, Rolling Stones ... all the big Icons - many more I can't even remember now.
I missed seeing Queen - that breaks my heart. Freddy died when I was in my early 20's. He was so secret about his illness, no one knew we were running out of time to see him.
