Beyonce Knowles delivered one hair-rising performance at the 52nd Annual Grammy Awards, belting out a crotch-grabbing act accompanied by a band of dancers dressing in LAPD SWAT costume. Beyonce actually could not get on stage to accept the award of Song of the Year because she was preparing for the particular performance.
Instead of singing her winning song "Single Ladies (Put a Ring On It)", Beyonce, who was introduced by Simon Baker, preferred "If I Were a Boy". But she followed it up with an angry song "You Oughta Know" which was popularized by Alanis Morissette.
Other performers of the night included Lady Antebellum who appeared behind a thin veil resembling a house while singing "Need You Now". They were introduced by the Jonas Brothers. Shortly later Zac Brown Band who won Best New Artist took the stage with the "legendary" Leon Russell, performing "America the Beautiful", Russell's "Dixie Lullaby" and the band's hit "Chicken Fried".
