Maya Rudolph will channel Prince at a sold-out, hastily put-together show with Jimmy Fallon’s house band the Roots in a hipster bowling alley tonight. The “Bridesmaids” star — whose mom was “Lovin’ You” singer Minnie Riperton — will perform a concert of tunes by the “Purple Rain” divo at Brooklyn Bowl. We’re told the show was finalized Tuesday, then sold out within hours. Questlove will DJ after. It’s not the first time Rudolph’s performed a gig, but it marks the debut of her all-Prince repertoire.
