Forgive the intrusion.  I probably posted the same thing last year about this time.  I saw Trans-Siberian Orchrestra again tonight and I'm still wound up.  Their show blows any away that this old rocker has ever seen.  In case you didn't know, I hit my prime in the 60's and 70's so I lived through a lot of rock and roll.

Since this is viewed round the world, who are some of the best music groups you've seen live.
