After 20 years and 23 No. 1 hits, country's bestselling duo wasn't going out without a party. On April 19 Nashville's brightest stars shared their love for the pair with a tribute concert, ACM Presents: Brooks & Dunn-The Last Rodeo, which will air May 23 on CBS. "They are a chapter in history that's going to stand for a long time, not just in country music-in American music," said Kenny Chesney
of the duo, who will go their separate ways after this summer's farewell tour. But Lady Antebellum's Charles Kelley, for one, is betting the split won't last: "I'm sure they'll be itching to do shows together. They'll probably pull a Brett Favre on us."
