Grammy Awards rehearsals: Taylor Swift sings with Stevie Nicks, DMB brings the energy
Grammy rehearsals are in full swing, and we now know which songs many of the stars will be performing tomorrow night at the 2010 Grammy Awards.
Taylor Swift, an 8-time nominee and prohibitive favorite, will be joined onstage by Stevie Nicks for the Fleetwood Mac track "Rhiannon" and Swift's own "You Belong With Me."
Album of the Year nominees the Dave Matthews Band will play "You & Me" with help from high school jazz musicians. The lively performance of "You & Me" will be much more entertaining than the sleepy "The Space Between" they played in their last Grammy appearance.
The Zac Brown Band will perform "Chicken Fried" with 67-year-old country/folk singer Leon Russell. Pink will perform "Glitter in the Air," a little-known track from her album Funhouse. Mary J. Blige and Andrea Bocelli are set to sing "Bridge Over Troubled Water," with proceeds from iTunes sales of the duet to benefit Haiti relief.
Green Day are scheduled to perform "21 Guns" accompanied by part of the cast of the American Idiot musical they inspired. Roberta Flack and Maxwell will duet on "Pretty Wings" and "Where is the Love." The Black Eyed Peas will meld their latest hit "Imma Be" with "I Gotta Feeling."
Bon Jovi will perform bits of three songs: "We Weren't Born to Follow," "Who Says You Can't Go Home" with Jennifer Nettles, and the song that fans vote for (barring a total shock, it's going to be "Livin' On a Prayer.")
