The name of the dancer that appears in the THK DVD is Mick Donegan.... and he's going to be on the tour!
Mick's represented Ireland in the Eurovision Dance contest, appeared on Celebrity Jigs 'n Reels (think Dancing With The Stars with step dancing), toured with Riverdance and Ragus... and a whole lot more.
