I am willing to agree that JOP plays the Savatage songs really well live, probably as good if not better than the Savatage guys did. However:
1) No Zak.
2) JOP hasn't produced one album I like as much as anything Savatage did from Gutter Ballet through The Wake of Magellan, aside from maybe Tage Mahal.
That's really the long and the short of it for me. It's not a matter of being ignorant/bitter, I honestly just think Jon and Paul O'Neill did/do all their best work together.
Also, some of my bitterness comes from the fact that if Savatage were touring, I might have accumulated more than 1 or 2 chances to see them within 150 miles of me within the past 6 years. I doubt JOP will ever make their way back into the Northeastern US.
