Jerry Lee Lewis – 85 years old
Jerry Lee Lewis is the man behind the rollicking hits Great Balls of Fire and Good Golly Miss Molly, to name just a few. His rock and roll suffered a real setback, however, when he married his 13-year-old first cousin. His career was able to bounce back with time, fortunately. However, despite this seeming recovery, he never achieved the same level of fame that he enjoyed early on ever again.
