Nothing is going right for 2 Live Crew. While the three members of the controversial rap group are facing obscenity charges in Florida, their Oct. 20 show in Flint, Mich., was canceled because the promoter would not pay for more security at the show as mandated by city officials. Shows in Jackson and Detroit also have been dropped, and authorities have threatened to arrest the rappers at their Oct. 21 performance in Big Rapids if they are obscene.
