Rap mogul Russell Simmons is the brains behind a hip-hop telethon planned for Friday night (09SEP05) to help the victims of Hurricane Katrina.

The Def Jam co-founder has persuaded Jay-Z to come out of retirement for the show, which will air live on America's BET network.

The concert will also feature Stevie Wonder, SEAN 'DIDDY' COMBS and Juvenile.
