Sunday's 59th annual Grammy Awards promised an "unforgettable tribute" to Prince and delivered, well, Bruno Mars performing costumed karaoke and an abridged set from Morris Day and the Time.

Mourning-tinged internet reaction policy dictates adjectives like "stirring" and "astonishing," but "passable" is more appropriate. For their part, Morris Day and the Time at least worked the stilted crowd at L.A.'s Staples Center with "Jungle Love" and the "The Bird." 

Then, the big moment.

Was Bruno Mars present onstage, wearing a Purple Rain-era blouse (Blue Ivy wore it better) and belting out Prince's "Let's Go Crazy"? Absolutely. Was it particularly spirited or touching? You be the judge.

Mars, clearly a gifted artist, takes us through the boiler-plate machinations of the song; extended guitar heroics, clearly red meat for Grammy viewers, made an obligatory showing.
