The Cure reissues with bonus discs?

[ZombieHavoc]

is the bonus material on the bonus discs of these reissues the same stuff that is on the box set or is it completely and utterly previously unreleased stuff?

if so, i may need to get these things.

From what I understand the second discs include rare demos, remixes, and unreleased material. I would guess the unreleased material is not found on their Join the Dots.
