Whitney Houston and Queen Latifah have joined Garth Brooks, Dionne Warwick, Burt Bacharach, Isaac Hayes, and Ray Charles as performers for the 72nd Annual Academy Awards, being presented on March 26.

As part of the show, the pop-country-soul ensemble will sing a medley of tunes that have been nominated for Oscars over the last 70 years, as well as the songs that are competing for this year's award for Best Original Song (see "Spike Jonze, Aimee Mann Nominated For Academy Awards").

According to "Variety," Bacharach and the event's musical director, Don Was, have already selected the songs that the group will perform, including "Alfie,'' which Warwick and Bacharach first performed at the Academy Awards back in 1967.

Bacharach and Was will also play in the backing band for the musical program, with Bacharach leading the group from his piano stool while Was mans the bass. Veteran session musicians will fill out the rest of the band.

To catch Whitney and Queen Latifah's Oscar performance, be sure to tune into the telecast of the 2000 Academy Awards, airing live on ABC on March 26 at 8:00 p.m. (ET)
