My DW got me hooked on them when we first started dating, and well be seeing them again Nov 18. I think itll be our 5th year in a row. I love the rock and roll elements, and my wife likes the story. So it works out well for both of us.
As others have stated, there are two touring groups. I believe both groups have a couple of the original members. The group that we get every year (which I believe is the West group) has Al Pitrelli and Tommy Farese, who I believe were both on the Christmas Eve and Other Stories album. And the narrator, Tony Gaynor, is outstanding.
Beethoven's Last Night was their first non-Christmas album. And they are working on a new one, but theyve been working on it for a couple years now. The last I heard was early 07, but again theyve been working on it for a couple years; so it is anybody's guess when it'll actually be released.
