Now that The Beatles have released "Now and Then," is there any chance that "Carnival of Light" will be next? I think it's the only Beatles track that hasn't been released now.
The link below has a quote from Barry Miles, who described what the song sounds like.

"The recording was described by Barry Miles, a long-term friend to Paul McCartney, and the writer of his authorised biography. Miles reportedly played a part in the genesis of the recording.
The tape has no rhythm, though a beat is sometimes established for a few bars by the percussion or a rhythmic pounding on the piano. There is no melody, though snatches of a tune sometimes threaten to break through. The Beatles make literally random sounds, although they sometimes respond to each other; for instance, a burst of organ notes answered by a rattle of percussion. The basic track was recorded slow so that some of the drums and organ were very deep and sonorous, like the bass notes of a cathedral organ. Much of it is echoed and it is often hard to tell if you are listening to a slowed-down cymbal or a tubular bell. John and Paul yell with massive amounts of reverb on their voices, there are Indian war cries, whistling, close-miked gasping, genuine coughing and fragments of studio conversation, ending with Paul asking, with echo, âCan we hear it back now?â The tape was obviously overdubbed and has bursts of feedback guitar, schmaltzy cinema organ, snatches or jangling pub piano, some unpleasant electronic feedback and John yelling, âElectricityâ. There is a great deal of percussion throughout, again much of it overdubbed. The tape was made with full stereo separation, and is essentially an exercise in musical layers and textures. It most resembles âThe Return Of The Son Of Monster Magnetâ, the twelve-minute final track on Frank Zappaâs Freak Out! album, except there is no rhythm and the music here is more fragmented, abstract and serious. The deep organ notes at the beginning of the piece set the tone as slow and contemplative."
So I guess the song sounds something like this:
