The Estate are refusing to promote Thriller 40

[Mike P.]

wondering if this is the reason why they used "mike's mix" for behind the mask
could that mean there is a superior mix / a quincy version they didn't wanna use cause of qj's involvement

I assumed "Mike's Mix" refers to the fact that "Behind The Mask" was already a pre-existing song by Yellow Magic Orchestra and that this demo was just the original instrumental with additional instrumentation and vocals provided by Michael.
