[1] It is a little-known fact that the Beatles decided their track
listing for their albums based on a process called the 'GEP' process.
After some initial problems, this worked very well. The only known
failure of this process happened when George Harrison commited the
out-of-place 'Within You Without You' to Sergeant Pepper without
review by the other band members. This near split-up led to one of
their finest songs on the world-reknowned White Album.
