In this week’s live episode, the remaining 14 contestants open the show with the 1983 Billy Joel hit “Uptown Girl.” Then, three new groups will perform timeless hits “Livin’ on a Prayer,” made popular by Bon Jovi, Cyndi Lauper’s “True Colors” and the... (more) Rolling Stones’ classic “(I Can’t Get No) Satisfaction.” Architects Emma Bunton, Nick Carter and Timbaland will critique their performances and select the bottom two who are up for elimination. Audiences at home will then vote, live, and decide who will stay and who will go.
