I suppose Kaye would have actually been part of the team that first created this wonderful song. I know he has no writing credit but the foundations for HOTS were definately in place while he was still in the band. It must have been fun for him to revisit it; I notice he stays loyal to Wakeman's additions though, quite considerate of him really. But he's still refusing to use as much synth, he loves that hammond too much!
Noticed Trevor made a couple of mistakes near the beginning, the rookie.
