American Idol legends came back together for this year's Top Five episode. Paula Abdul and Randy Jackson returned to the show on Monday, May 4, as did several contestants from the 2006 season, with the episode bearing a "Class of 2006" theme, a.k.a. a 20-year reunion. Jackson acted as a mentor for the last remaining contestants as they prepared for their Top Five performances, coaching aspiring singers Keyla Richardson, Hannah Harper, Chris Tungseth, Braden Rumfelt and Jordan McCullough.
