As the 45th annual Country Music Association Awards are approaching on Wednesday, we always look back at winners from years past. Some of them have us scratching out heads....(Olivia Newton John)and some have us cheering for more (Darius Rucker). We have past winners who have crossed over and jumped on the country music band wagon for a while, and some have stuck around for the duration of their careers. But lest we be too judgemental, remember that Conway Twitty, Patsy Cline and Kenny Rogers all had success on the pop charts too.
