Prince Reportedly Backstage at Toronto Alicia Keys Concert

In a review of the Alicia Keys concert in Toronto, the National Post reported that Prince was apparently watching from backstage. As they wrote,

"It was a slick spectacle that would have done Prince, who was reportedly watching from backstage, proud, particularly during a too-long version of his B-side ballad How Come U Don't Call Me, during which a phone booth and street lamp were rolled out merely to provide a punchline (Keys ends the song by dialing up her man and hanging up when he answers)."
