Saw Guthrie last december live for the second time. Needless to say that it was amazing (but I did it anyway). Also a really nice and down to earth guy, very approachable. He and Ron are (unquestionably) the guys that have it all in the biggest way possible....untouch able...
-PEACE-
Damnit! I've never seen them live, I hate that fact. And I most likely never will because they certainly won't come to Brazil

I'll see them only if I fly to the states (or London). As much as I like Ron in Guns he ain't doing solo tours anymore and that's a pity.
They are technically good...I enjoy watching Guthrie, but I lever listen to him.
His work (solo and with The Fellowship, Asia, GPS, etc) is great, but its not your standart...
chicken dinner 
I haven't listened to his work with The Aristocrats though... gonna listen to it eventually.
