Leave it to the Boss.

Bruce Springsteen and the E Street Band opened their Saturday show at Brooklyn with a touching, emotional tribute to Prince, covering his immortal “Purple Rain.”

As NPR put it: “Bruce’s effort to maintain the song’s building intensity was visible; it felt like it originated from a sense of loss, an expression of the emptiness that accompanies the departure of a kindred spirit more than the original song’s timbre of romantic loss and regret.”

The Boss ends the song with “Prince forever! God bless!”

Thank you Bruce; thank you Prince.
