I must be out of the loop. I didn't know Ryan Adams was "clean." Actually, I didn't think he was that "dirty" in terms of drugs to begin with. I knew he drank a lot.
Suede (better on drugs.)
Oasis (better on lesser quality drugs. Once they were able to get top-shelf blow it was all downhill ("Morning Glory"/Be Here Now/etc.))
Ummm...Ozzy? (better on drugs.)
Since my dad is a gym/health teacher and preaches "Just Say No!" I HAVE to come up with someone who was better clean...(I actually had a dream last night in which my father was buying $20,000 worth of heroin but I digress...)
Oh, the first Black Grape album (Shaun Ryder.) Better clean. That was better than any Happy Mondays album.
