Tweekgeek I just noted your post. I saw them this evening in Melbourne Florida. The show was fabulous although I thought they were a bit overamplified, always one of my pet peeves in such a venue.
For added flavor they had a local group of young clogging students and a local Harp player. The musianship of this group is absolutely incredible, no wonder everyone wants to jam with them. Indeed Allison Moorer has a very distinctive voice at once both powerful, and rich with wonderful pitch and tone. My wife, a singer herself was quite impressed and she isn't very easily. Highly recommend this tour to Chieftain fans and non fans alike, you won't be disappointed.
