The disco ball swung on American Idol Wednesday night and knocked out contestants Lil Rounds and Anoop Desai. Though both were frequent bottom dwellers, Desai especially seemed shocked at his elimination. Rounding out the bottom three was Allison Iraheta, who has continually won favorable notes from the judges but finished below Matt Girard. The night also included Paula Abdul’s choreography for the opening group song of the disco-themed night. Former Idol runner-up David Archuleta performed his song “Touch My Hand.” (Photo: WENN)
