There's Mandolin on All The Midnights In The World.
Since that's one of the instruments listed as being played by Wendy, we can assume that's her on this song.

And only one song with a bit of percussion (Chelsea Rodgers), so I'm guessing that's where Sheila E is hiding

and then there's this:

First single 'Guitar' ought to be the cause of rejoicing - it features Wendy & Lisa, Prince's long-forsaken female bookends from the Revolution. It opens with the line 'getting dirty at the club again', marking a Princely return to raunch in his lyrics after a long spell of pious modesty. But while it is undeniably catchy, imbued with just enough mischief to identify it as Prince, 'Guitar' is disappointingly shallow. Another Wendy & Lisa link-up, 'Lion of Judah', is all moody galumphing.

The core of Planet Earth is hotter. Featuring Wendy Melvoin on acoustic guitar, 'The One U Wanna C' is a classic of Purple wooing, deploying girl-group harmonies, lots of tremolo and the kind of friskiness you daren't hope the 49-year-old still had in him. Falsetto soul turn 'Future Baby Mama' finds Prince taking on young love-bucks such as Usher, rising to a climax of multi-tracked sighs. Even more lovelorn is 'Somewhere Here on Earth', a classy affair in which piano and saxophone have meaningful intercourse. 'Mr Goodnight' finds dirt back on Prince's mind.
