Eight singers sang backup for the season nine winner during his soulful rendition of "Hallelujah."
The season three winner's fate was pretty much sealed after she killed it during her pitch-perfect performance of George Gershwin's "Summertime." Randy even declared it "the single best Idol performance of any season I've ever heard."
