After waiting almost a year to hear a completed track from Amy Winehouse, Quincy Jones has had to cut the singer from an all-star tribute album being recorded in his honor, the Mirror reports. Producer Mark Ronson, who’d been working on the song with Winehouse, tells the Mirror, “The track isn’t finished and she’s not around. If she’s not here then, unfortunately, there is nothing we can do about it.” Winehouse is said to be working on a documentary, “a truthful and revealing look at her complicated life.”
