We’ve already heard Adam Lambert slay Lady Gaga’s “Marry The Night” and now we get to hear him take on a Katy Perry track. How nice of Ryan Murphy to not force Glambert to take sides on Glee’s episode, “A Katy or a Gaga.” So nice ;)

Joining him on Perry’s “Roar” is guest star Demi Lovato. While I love both Demi and Adam, I’m not a huge fan of the track. I would’ve preferred them collaborating on another Katy track. “Unconditionally” and “Dark Horse” are far more superior off her latest album, Prism. In addition to their “Roar” duet, listen to the Glee cast cover Gaga’s “Applause” and Katy’s “Wide Awake” below.
