Who Was the Most Prog Beatle?

This. Don't know exactly why I voted George except for the Indo elements.

Often called the 5th Beatle we all know the influence George Martin had on the Beatles recordings but we tend to overlook that he was a composer and musician. That piece of electronic music, (later recorded by an orchestra and later still by a little known Prog band by the name of Van der Graaf Generator), contains everything he brought to that party to the extent that it actually sounds like a collage of dozens of Beatles records - there's bits of Revolver in there, bits of Sgt Pepper, bits of Magical Mystery Tour - the trumpet refrain, the sawing cellos, the organ crescendo, were all musical touches that Martin the musician introduced into those Beatles tunes that lifted them above the ordinary. To me, Martin with the Beatles was like Wakeman with Yes: Anderson, Squire & Howe had the tunes and the ideas, but it was Wakeman that brought those disparate ideas together with his musician's touch and expertise. John, Paul & George had the tunes and the ideas, but it was Martin that brought those ideas together because he was a musician as much as he was a producer - he made the Beatles sound "proggy" (for want of a better word).
