I think had Ross83 been a better album, the Central Park show would've boosted sales through the roof. Officially I wonder how the sales were doing pre-CP and afterwards. Would be very interesting to see if the album got a boost at all. I imagine it did. Had Diana managed to snag Quincy or even Lionel to helm the entire 83 album, with the tie in to Central Park, Diana might have had the biggest album of her career.
