So this is interesting, might have no relevance to the doco but who knows. I was at JB Hi-Fi a few hours ago and whilst browsing, went through the CDs. I noticed the spine for 'Off The Wall' was different (blue text on black) so I pulled it out and for some reason, they had a brand new CD using the original artwork, not the Special Edition artwork.
(Not the best photos, you can thank the lights above me)
But what peeked my curiosity further was the fact that they were reissued this year, as you can see in the close-up of the back it states "© 1979, 2015". There's no new material, nothing that special about it so I have a feeling it might be part of some Sony/Epic 'Legacy' Collection or something (like "Michael Jackson Icon" or "20th Century Masters") but I couldn't see any other albums like this and none of MJ's other albums seemed to have been reissued this year. Makes you wonder why they reissued it...
