Charles Kelley of Lady A opens up about his journey to sobriety: "I can't really say I'm sorry enough"

Lady A, the chart-topping country music trio, has been making music together for 17 years. However, in August of last year, the group postponed their tour to allow bandmate Charles Kelley to seek treatment for alcohol abuse. 

Kelley, who has won seven Grammys with Lady A, revealed exclusively to "CBS Mornings" that behind the scenes, his relationship with alcohol was taking a turn for the worse. 

"I remember joking, you know, with buddies," Kelley said. "I was like, 'Yeah, I'm definitely a functioning alcoholic.' And I said, 'I know I'm gonna have to stop at some point, but that's not today.'"
