Not sure... The Beach Boys seemed squeaky clean at the beginning of their recording career. By the time Smile and Pet Sounds came out, I think people knew about their drug taking (great albums!!!) but many who know their early work have never heard "Our Prayer" for example. I think they got their fame on the G-rated stuff and were able to push genre boundaries later. I think it's the same with The Beatles, although I'm not positive- hard to imagine a time when people were not familiar with Sgt Pepper and The White Album...
