Alan Jackson and the late Johnny Cash were the big winners at last night's CMA awards. Alan took home awards for Entertainer and Male Vocalist , and shared the Vocal Event award with Jimmy Buffett, his singing partner on the hit "It's Five O'Clock Somewhere." Johnny's album American IV won Album and "Hurt" won both Single and Video of the Year. A gracious Martina McBride repeated last year's win in the Female Vocalist category, while Brooks & Dunn surprised no one with their Vocal Duo win. Rascal Flatts won Vocal Group of the Year - and tried to give their award away to Alabama. Rising star Joe Nichols took home the Horizon Award.
