Rather than have one Teen Angel, a role originally performed by teen crooner Frankie Avalon, the three remaining members of Boyz II Men will perform the role as a trio, singing "Beauty School Dropout." On their Twitter account today, the group announced, "We're so excited to announce we're joining Grease: Live."

The tweet also included a video of members Nathan Morris, Wanya Morris and Shawn Stockman singing a brief a cappella version of "Grease is the Word." It sounded angelic, naturally.
