It came not on a significant birthday (he would have turned 68 earlier in the week), nor was it a round-number anniversary of his death (on May 11, 1981), the original release date or first charting of any of his cornerstone albums or singles. Recording Academy officials note that the soundtrack album for the recent "Marley" documentary about the reggae star had been nominated in the compilation soundtrack for visual media. But the back story I got from longtime Grammy show executive producer Ken Ehrlich is that it grew out of his wish to lure Bruno Mars back to perform this year. Mars had originally communicated his intention to sit out this year's Grammy show, Ehrlich said at a rehearsal last week, with the aim of "owning" next year's show. "I said, "If I came up with a concept he liked, would he consider it?"" Ehrlich said. He said he would. Ehrlich contacted representatives for Sting and Rihanna about having them be part of a Marley tribute on the show, knowing each artist held a fondness for reggae in general and Marley's music in particular. That led to invitations to Marley scions Ziggy and Damien, and a blessing from their mother and Marley's wife, Rita, all of whom approved. "At that point I went back to Bruno and said, "Here's what I've got - are you interested?"" Thus Sunday's mash-up of Mars" "Locked Out of Heaven," Sting's Police-era number "Walking on the Moon" and Marley's "Could You Be Loved," a track from the final album released before Marley died, "Uprising."
