There have been 4 Beatles Super Deluxe Sets Giles Remixed (Sgt. Pepper has 4 CD's, The White Album has 7 CD's, Abbey Road had 4 CD's, and Let It Be has 5 CD's) They also have DVD's and Blue Rays which include 5.1 surround sound mix's and an HD version of the album. The ones that were also mastered mono have the mono mix on the DVD and Blue Ray. The extra discs have out takes, and in some case alternate takes. The legendary Glyns John did a totally different mix of Let It Be that is not that great and I can see why The Beatles rejected it for release. So back to out takes. It like the stuff on the Anthology CD's. Works in progress, just backing tracks with no vocals, takes that have mistakes, or the lads cracking up, ect.
You can also buy just the remixed CD or a CD with one extra disc of out takes. The White Album's extra disc has the entire Esher Demo's recored at Georges after they came back form India. Ringo has no sone on the Esher Demo's but I am sure he was there when it was recorded.
