All of the core Savatage musicians (Plate, Pitrelli, Caffery, Middleton) are involved in TSO, in either the East or West touring group. There are 2 separate groups because it's the only way to cover the entire country in less than 3 months. Plate and Caffery are in East, Pitrelli and Middleton are in West. No Skolnick again this year for East coast, though. I don't even think Hoeskstra's in either.
