"It would be cool to see them tour with Metallica!"
Metallica would most definitely have to open for TSO... Yeah, TSO's creators are certainly from the rock world..
In fact , you can see the "latest" members from 1997's Savatage all playing on the original "Ghosts of Christmas Eve" dvd on You Tube..
In the Seattle show, Al Pitrelli is the coordinator, lastly, he played with Savatage and Megadeth.. Johnny Lee Middleton was there, (Savatage), and Jeff Scott Soto was singing as well..
On the East coast tour, you have Jon Oliva, Chris Caffery, Jeff Plate, Zac Stevens All from Savatage play.. And of course, the creator and head honcho Paul O'Neill has produced Savatage since 1987's Hall of the Mountain King... They started TSO in 1997 for a Christmas Project and it immediately took off around the entire country and just grew into the incredible show that it is now...
I was talking to Johnny Lee after the show and He said they are working on getting Savatage back up and running.. cool!...
