Jerry Lee Lewis of early rock 'n' roll fame was also one of the first in that genre to get his name into several scandals involving his marriage to a distant cousin,etc.
Another cousin, Jimmy Swaggart, got quite a ways up the ladder as an evangelist/singer before his escapades with some shady ladies brought him down.
In the midst of all this, Mickey Gilly comes off as the one who seems to stay out of trouble.
I had the pleasure of meeting Mickey when I interviewed him at a Chicago radio station back in 1980. (WJJD/WJEZ....both have new call-letters now: WSCR & WJMK respectively) and he seemed to be surprised by the "Urban Cowboy" movement taking place in country music. He seemed to be "surfing" on the fame more than contributing to it. He rode that wace until it dissipated.
