I concur. I've seen them three times and going for my 4th next month.
First time I saw them was in '87. They ALWAYS put on a great show, always. (sheesh, I'm showing my age). I still am and always will be a huge Def Leppard fan.
I've seen them 5 times now. They headlined Jingle Ball in december here in San Diego. I hope to see them this summer in Dallas when I'm home. Talk about not being able to hear a thing after those shows. heh heh. :)
