Last I saw them was '96. But the '92/'93 tours were what I remember. I was third row center for the '93 show and I got a stick point and a wink from Carl during the show, and seeing Greg Lake from 10 feet way singing Pirates ("Six days, off the Cuban coast...") was transcendent.
I saw them in August 1992 (my seat was not as good as yours). They closed the main set with Romeo & Juliet, Lucky Man, Pirates and Pictures at an Exhibition. That was fucking surreal!
Saw them on that tour as well. That was the same week that I got DT's Images and Words on cassette and I couldn't wait to show this cassette to my Dad and be like, "Dad, this is what ELP is inspiring!" Unfortunately, my walk-man ate not one, but two cassette copies of Images and Words and I was so disappointed!! Saw them in Cleveland and Detroit on back-to-back nights. Sets were the same, but ELP was on fire for both!
Last time I saw ELP was in 1998, I think. I think it was on their tour with Deep Purple, and Dream Theater opened.
