Here's a rundown of the musical acts on tonight's Grammy's show. The LA Times asks the big question: will Sly Stone actually show up for a tribute to him? My favorite quote comes from Jamie Foxx as superstars stand around for an hour waiting for Sly to pop in for the run-through. "This isn't the Source Awards, right?" says Foxx. "You show up, you do it and you do it right. This is the Grammys. This is the real thing."
Madonna and Gorillaz open doing a medley of "Hung Up" and "Feel Good Inc." A tribute to New Orleans features Allen Toussaint, Dr. John, Irma Thomas, Elvis Costello, Bruce Springsteen, Bonnie Raitt, Bono, The Edge and Sam Moore of Sam & Dave. Linkin Park and Jay-Z duet, as do U2 and Mary Blige, Faith Hill and Ketih Urban, Christina Aguilera and Herbie Hancock, and Jamie Foxx with Kanye West. Paul McCartney and Kelly Clarkson perform solo. Dave Chappelle intros the Sly Stone tribute, which includes Joss Stone, Ciara, Will.I.Am of Black Eyed Peas, Maroon 5, Van Hunt and Joe Perry of Aerosmith. I think the Cinderella story of the night for the performers will be Clarkson, who as proven with album sales she's a legitimate artist, but this Grammy solo shot confirms it to the world.
