One of the two IROC Z28 Camaros signed by 50 rock and television stars at last July's Live Aid concert in Philadelphia is coming to town, part of a "Drive Aid" promotion sponsored by Chevrolet, MTV and Radio City Music Hall.

The car will be displayed at the National Capital Area International Auto Show at the Washington Convention Center Jan. 15-20 as part of an eight-city tour. During January, radio station Q107 will run a sweepstakes concurrent with contests in seven other Northeast cities. The eight winners will end up at Radio City Music Hall on Feb. 20 for an all-star Drive Aid concert. They also get air fare, hotel accommodations, a backstage tour, lunch with an MTV veejay, and an MTV tour jacket (be still, my heart!). One of those winners will leave the show A Big Winner -- in the signed Camaro.

Money from the concert at the 6,000-seat Radio City Music Hall will go to the Live Aid Foundation. Bob Geldof, founder of the Live Aid and Band Aid hunger-fighting organizations, said yesterday in a statement from London that "the foundation, Band Aid and I support this effort to raise funds to fight world hunger."

Negotiations are already under way with such potential concert performers as Sting, the Hooters, Bryan Adams, Loverboy, Howard Jones, Simple Minds, INXS and Geldof's own Boomtown Rats, who might use the opportunity to audition for record companies after being dropped recently by CBS.

At this point, MTV has no plans to televise the concert, though that could change as the acts firm up. In addition to ticket sales (no prices or sale dates have been announced), money for Live Aid will be generated by notices on posters and registration cards available at Chevy dealers.

"They'll have language to encourage everybody that registers to send a donation to Live Aid," said Bill Girard, a marketing manager for Chevrolet. "We really don't know what kind of results we'll get from that, but we're confident we'll raise a substantial amount of money."

The other rock 'n' roll IROC is still sitting in Detroit while Chevrolet figures out a way to use it to raise more funds for Live Aid. Among those who signed the cars: Mick Jagger and Keith Richards, Rick Springfield, Don Johnson, Patti La Belle, two Duran Duranies, three Beach Boys and all Four Tops, Crosby, Stills, Nash and Young and several appropriately named folks -- R.E.O. Speedwagon, two Cars and Chevy Chase.
