The Rolling Stones have welcomed several guests onstage for their ’50 & Counting’ tour: Lady Gaga for "Gimme Shelter," Tom Waits for "Little Red Rooster" and John Mayer on "Respectable." For their third and final night at Chicago’s United Center, the band revealed on their Twitter account tonight's special guest: "Tonight's special guest will be @taylorswift13!"
What will they play together? A country song like "Sweet Virginia" or "Far Away Eyes"? Or an upbeat warhorse like "It’s Only Rock & Roll" or "Tumbling Dice"? A good bet might be a song somewhere in the middle: "Honky Tonk Women."
Swift is no stranger to nightly collaborations – on her Speak Now tour, she covered new songs in every city and performed with guests including Justin Bieber, Flo Rida and James Taylor. She resumes her Red tour on June 14 at Toronto's Rogers Centre.
