Jamie is the bagpiper and he started the group back in 1996 I believe. I never have known them to roatate musicians, Jamie has always been on pipes, Mark on bass, Randy on guitar, Tony on keyboards and Scotty on drums. Thye have 2 c’ds I know of and I bought 1 on a visit and had them autograph it. So as far as where he was not sure for that particular performance. They are great guys and you should check out their website, www1.offkilter.net.
