Brown is credited (in the OP's link) for Prince of B'way's "musical supervision and arrangements". I wouldn't expect much (if anything) in the way of original composition, unless it's along the exceedingly-slender lines of the single original ditty ("God") composed by Himself for Sondheim on Sondheim a few years back.
As I understand it, PoB is very much a greatest-hits compilation -- that's its point, like SoS (or a little more closely, like Jerome Robbins' B'way back in 1987). Whatever thematic through-line Prince may establish to make sense of his own career, I wouldn't expect "new" material in any significant quantity beyond, at most, connective tissue.
But what do I know? I'm just guessing.
