You knew it was coming...
Yes was highly influenced by Stravinsky and totally lifted Holst's Jupiter for "The Prophet." King Crimson was influenced by Stravinsky and totally lifted Holst's Mars for "The Devil's Triangle."
However, to repeat an old argument, if we're talking about adding classical music, however "weird," to a rock station because of it's influential status (not to mention that it's "art"), then we should also add some of the weirder modern jazz like Charles Mingus and Modeski, Martin, & Wood - as well as some of the big influential jazz acts. It is well known that Steve Howe was hugely influenced by Django Rheinhardt and Wes Montgomery. If the classical is being considered based on it's influence on prog rock, then we also have to look at Roy Samek, Chet Atkins, and any folky stuff that influenced the likes of Steve Howe and Genesis, or the blues men that influenced Floyd.
Of couse this is and absurdist-styled argument, but you get my point. I'm two-cents poorer again...
