Kenny Chesney, Brad Paisley and Sara Evans were among the several stars who performed for radio representatives Thursday (March 6) on the Sony BMG's annual party during the Country Radio Seminar. The lavish event, which included a formal dinner and cocktail party, was held on the General Jackson showboat on Nashville's Cumberland River. At the start of the program, label officials announced that Sony BMG has signed former Broken Bow recording artist Craig Morgan. Other performers included Jypsi, Chuck Wicks, Kellie Pickler, Miranda Lambert and Chris Young. Circulating through the audience but not performing individually were Gretchen Wilson, Pat Green, Montgomery Gentry, Blaine Larsen, the Lost Trailers, Keith Anderson and Crystal Shawanda. Chesney invited all the artists on stage to help him close the gala with a ragged but enthusiastic version of the Rolling Stones' "Honky Tonk Women."
