Chris Sparks And Richard Thompson Announce Team Cul De Sac Go here for the announcement as worded by Richard Thompson on his fine blog. This is a fund-raising effort for Parkinson's research, and involves using Thompson's Cul De Sac characters by any artist that wants a shot at them in just about any way imaginable, all for a book project that will be sold to raise money for the cause. Thompson's announcement that he has Parkinson's Disease in the summer of 2009 stunned the professional community, and he's talked about the diagnosis and subsequent treatment with his usual charm and class ever since.
