As much as we sympathize with the cause, we want to hear him spin, not lecture. No problem. The only politics at Club Space this Saturday will be The Politics of Dancing, Vol. 2. Van Dyk's live set is a release party for this new CD. Mr. In-Demand has a gig in New York's Central Park from 6:00 to 10:00 p.m. "My bags are waiting behind the stage," he explains, "and ten minutes after I'm done, I'll be in a car" -- to catch a private jet to Miami for his 2:00 to 5:00 a.m. engagement.
