NASHVILLE, Tenn. (AP) _ Country Music Hall of Fame singer Mel Tillis is recovering in Nashville after heart surgery over the weekend.

According to a statement from his daughter, Pam Tillis, the 81-year-old singer required a ``routine heart procedure,'' but is expected to make a full recovery.

``In typical Mel Tillis fashion, he's already cutting up and cracking jokes with the nurses,'' Tillis said in a statement. Four scheduled shows have been canceled due to his surgery.

Tillis became a successful songwriter and singer despite dealing with a stutter. He has recorded more than 60 albums. His hits include ``Good Woman Blues,'' ``Coca Cola Cowboy'' and ``Southern Rain.'' He's written top songs for George Strait, Ray Price, Bobby Bare, Kenny Rogers and many more.
