Agree with the above-mentioned request for demos and alternate versions that genuinely date to 1986/1987. I assume those will surface on the 40th anniversary edition. (Fair disclosure - I have bought, and will continue to buy, all of these reissues, so I guess I must not be too unhappy with what they are offering).
On another note, I love the alternate white album cover. I wish/hope the deluxe LP set was/is going to include that variant.
