With all due respect, he was okay....however Panchi of The Stingers chills me with his voice it's so like Klaus'. But that's MY opinion.
Also, you don't HAVE to sound like Klaus to be a great tribute band. Savage Amusement, whom James sat in with as a guest last year, thought they were great. Especially Wes' voice, which does NOT sound like Klaus' and doesn't try to cuz he sings like himself. He also is in an Iron Maiden tribute band cuz his voice is so amazing. The rest of Savage Amusement guys *The Savages* are fantastic and Kevin plays just like Matthias. So...it's a matter of perspective. I remember at one point when James was sitting on my chair arm with me during a break for him and he just stared at the band playing and said "whoa". I sent videos to MJ as well.
So what I'm saying simply is that we have our faves and as long as there are bands that are continuing the legacy, when our boys are gone, we will have bands that will keep us a little satisfied. However, nothing will keep us fully satisfied when Scorps are no more.
