They were split into two groups and performed on separate days at the Orpheum Theatre in Los Angeles.
They were separated into groups of males and females, but they performed solo with piano accompaniment and back-up singers.
The songs for the groups were Four Tops's "I Can't Help Myself (Sugar Pie Honey Bunch)," The Temptations' "Get Ready," Barry Manilow's "Jump Shout Boogie," The Marvelettes's "Please Mr. Postman," and The Supremes' "Where Did Our Love Go."
At the Pasadena Civic Center, each contestant took the elevator from their holding room to the floor above to see the judges, who then revealed their fate.

Each contestant performed two songs: one written by songwriting duo Jerry Leiber and Mike Stoller, and one from the Billboard current chart.
Simon Cowell believed that Bo Bice would have won had he able to save his a cappella rendering of "In a Dream" for his final performance.
