It's well known Richard had addition problems in the late 70s (with no knowledge that the substance being used recreationally). I think what plagued both KC and RC was being overworked. Doing an album ever year, touring, tv shows, promotion, videos/photoshoots, meetings and interviews etc. is tough. No matter how successful you are, that's hard work all-in-all. It's for this reason I'm glad he's doing things in his own time. I didn't think it was possible (only deducing that this idea would be fit for their legacy), but he proved us all wrong. Now that he's over a recent lawsuit or negotiations he was dealing with Universal he's back at it! I can't figure out if this new project is using digital transfers or what... Anyway, I think control issues have always been a struggle for The C's, but whatever compromise/deal was made let's just be happy for this news.
