I saw Def Leppard in concert 6 months ago.....
Many bands where the lead singers hit high notes crumple when singing live, especially after they've been at it for awhile, as you only have so many strained high notes in your voice, but they did a great job of hitting most of them....and they were awesome...
Of course, if I was still 14 years old, I would say; "The Scorps Rule dude!" lol
