Off Kilter is a Disney creation. Jamie (bagpipes) had already been playing in the Canadian pavilion with a drummer - both wearing white shirts and kilts with the Nova Scotia tartan and walking through the gardens and up to to the NW Mercantile where they would play a small show.
Disney wanted to up the ante a bit and found other musicians (some already worked for Disney, like Randy - some did not) and worked out a more of a celtic rock band. Jamie and Mark tried to figure out some traditional Nova Scotian songs to do that they could spruce up so he asked an amazing, attractive, talented, awesome, sweet, intelligent...oh, ok it was me
Nova Scotian girl who worked at the pavilion to give a couple of song suggestions.
They began rehearsing (which I snuck into a couple of times) and then they played their first show for Disney execs (and a few of us Canadians for support) as an audition to see if they band would work. The execs loved it and the band debuted at Disney in 1997.
They did not exist outside of Disney until after that.
