The 2011 Oscars rolled out the red carpet on Sunday (Feb. 27), and this year's awards brought back the one thing music fans missed the most in 2010: "Best Original Song" performances. This year, Gwyneth Paltrow belted out "Coming Home" from "Country Strong," Zachary Levi and Mandy Moore dueted on "I See The Light" from "Tangled," Florence Welch from Florence + The Machine took on "If I Rise" from "127 Hours," and Randy Newman tugged heartstrings with "We Belong Together" from "Toy Story 3."

So while discuss what song grabbed the golden statuette on Sunday, we're looking back at the 10 most amazing live music moments the Academy Awards have ever broadcast. The Oscars simply would not have been the same without Beyonce and Jennifer Hudson's a battle of the "Dreamgirls" divas,  Michael Jackson's teenage serenade to "Ben," or Madonna homage to Marilyn Monroe.

As fellow Irishman and Oscar presenter Colin Farrell put it, U2's "The Hands That Built America" honors "new Americans who left Ireland in search of a better life, willing to fight for it at any expense." Written for Martin Scorsese's "Gangs of New York," the song ultimately lost out to Eminem's "Lose Yourself" but provided a rocking awards show performance nonetheless. Footage of immigrants entering Ellis Island splashed across the stage's backdrop while Bono belted "Hallelujah," creating an Oscar moment of epic proportions as only he can.
