Broadway veterans Matthew Morrison and Lea Michele just can't seem to get enough of The Rocky Horror Show. After Glee's recent own Rocky Horror-centric episode Morrison and Michele took the stage at an October 28 Los Angeles benefit concert that paid tribute to the cult musical on the 35th anniversary of its film adaptation. While they may have a student/teacher relationship on TV, the duo moved up to sweetheart status to play Rocky Horror's naive young lovers, Brad Majors and Janet Weiss. With the movie playing on a big screen behind them, the pair took on the campy tune "Damn It, Janet." Take a look below and just in case you missed it, we've got Glee's rendition on the song too!
