Van doesn't own the rights to his first three albums: Astral Weeks, Moondance, and Band & Street Choir, Warner does. From what I heard, they tried for a long time to make nice with Van so that he'd let them distribute the rest of his back catalog from Tupelo Honey onward, but that never happened. I guess they figured that whatever bridge was there had been burned, and decided to put out this deluxe version of Moondance. Morrison took to his website to issue a statement urging people not to buy it because he hadn't approved it and complaining that he was still being ripped off 45 years later.
