Mick Fleetwood and Stevie Nicks are among a slew of celebrities scheduled to perform at Andre Agassi's star- studded Grand Slam for Children benefit concert in Las Vegas on Sept. 26.

The fourth annual event, which will take place at the MGM Grand Garden Arena, will also feature performances by soul singer Lionel Richie and comedian/ actors Dennis Miller and Robin Williams, among others. At press time, there were no plans for the rest of Fleetwood Mac to show up with Fleetwood and Nicks, according to the band's publicist.

For the fourth year in a row, Grammy- Award winning producer, arranger, and composer David Foster will handle musical directing duties for the Grand Slam for Children concert, which will help raise money for the Andre Agassi Charitable Foundation -- a not- for- profit organization founded in 1994 to assist at-risk youth in Agassi's hometown, Las Vegas.

In addition to the concert, the AACF is also hosting a black tie dinner gala and two auctions. The silent auction will feature memorabilia donated by Elton John, Celine Dion, Dennis Rodman, and Tiger Woods, while the live auction will offer a dinner in San Francisco hosted by Robin Williams, a recording session with country crooner Tim McGraw, a day on the greens with gold legend Arnold Palmer, and Bill Cosby's very own Infiniti Q45.
