As one of those twisted freaks who considers "Revolution 9" one of my top 10 Beatles songs of all time, I had to notice this.
In one of John Lennon's final interviews, he explained how "Revolution 9" began: "The slow version of 'Revolution' on the album went on and on and on and I took the fade-out part, which is what they sometimes do with disco records now, and just layered all this stuff over it." Supposedly, this is the original 10:47 take of what became "Revolution 1" with screeching psychedelic guitar drones, shoo-be-doo-wop harmonies and John primal-screaming and panting (all the unnerving shouts and gurgles that percolate through "Revolution 9"), and a segment of the murky, highly-distorted last few minutes of the latter song/collage stuck at the end. (The bit after "take this brother, may it serve you well" always sounded like a completely separate piece recorded on cheap equipment by John & Yoko, compared with the previous six minutes of frighteningly vivid tape loops, so it's plausible that smaller bit was always intended to a part of the original "Revolution".)
BUT...is this for real? These days, some creative electronic wizards specialize in mash-ups, throwing separate songs together for copyright-infringement comedy fun; there are even dance clubs devoted to this stuff. So is this really just some seamlessly-edited Frankensteinian fantasy of lost Beatle-lore, a Piltdown Man of Merseybeat? Or is this a genuine, rejected version of a Beatles song? The main body of the song is SO similar to "Revolution 1" that I'm a tad suspicious. But I'm not sure how much I really care about the track's authenticity; at the moment, real or fake, it's become my favorite version of "Revolution".
