Another great 'Tron track here on the Moon is Symphonic Holocaust by Morte Macabre (An Anekdoten spin off I think).

I remember reading a Moody Blues article where Mike Pinder said that his 'tron was always breaking down and one time had to be fixed quickly using a wire coat hanger.

Some of Rick's work on TRSoG from "Tales" is amazing too. Such a good sound that today's electronic strings can imitate but not replicate.
