Glen Campbell lived through a boozy, cocaine-fueled decade in the '70s (and early '80s) to later find God and a good woman and enjoy a career rebirth that only wrapped up recently. The singer admits to spending nights snorting cocaine and drinking before coming home angry to whichever wife he was married to at the time, including Tanya Tucker. "In our sick slavery to things of the flesh, we were either having sex or fighting," he said of that marriage.

He eventually quit using drugs when wife Kimberly Woollen threatened to leave, and then quit drinking when she recorded his drunken ramblings and played them for him. He's relapsed since, including a 2003 arrest for driving drunk in Arizona.
