Joan Rivers will offer her unique take on country music when she hosts the special, CMT 40 Greatest Done Me Wrong Songs. The two-hour special will count down the best cheating, backstabbing and revenge-filled country songs ever recorded. Providing their own perspectives will be two actresses known for their TV roles as the always-wronged woman — Linda Gray of Dallas and Morgan Fairchild of Falcon Crest. CMT 40 Greatest Done Me Wrong Songs debuts Saturday (Sept. 18) at 8 p.m. ET/PT.
