What about Wayne Newton or Lawrence Welk?
I posted this thread. I was not a fan (or listener) of Ozzy's until his latest show "The Osbournes" wherein Ozzy comes down hard (and tells all of his listeners to avoid) drugs and alcohol.
But I am sure you are the judgmental type ... you do not forget. Once a druggie, always a druggie. But I hope you take a look at many, many of the lives of the saints who recovered from terrible faults and redeemed themselves. Mary Magdalene (sp) for instance.
I suspect you think you are "perfect" ... or are on the way to it. At the same time you stop to pass judgment on your fellow travelers.
