They re-released LIB last year without the wall of sound mix. To be honest, I never got around to buying or listening to it. It's still on my list.
Abbey Road still gets PT in my CD player.
If you really want to get into the artistry of the Beatles, one of the best ways to do it is to hop onto Kazaa or Limewire and, ahh, download for personal use only any of the Beatles' bootlegs or out-takes. Listening to them "compose" in the studio gives you shivers.
