Alba they change it for certain episodes, there is a much softer sounding ending akin to that... I can't find it though... I have that full version down on my PC... I'm not sure if I'm too keen on it either.. but after watching the show it's usually a case of wow... and wonder which one they'll sound off with following that.
I think whoever decided on Kansas and Wayward Son got it absolutely bang on the money tho :-)
(Sorry for digression mamya)
Can't remember what I was looking for in the first place now lol x
