Former Glee stars Grant Gustin and Melissa Benoist are bringing their singing skills to the DC-CW verse in the upcoming The Flash musical episode, "Duet," and the network has released the first trailer.
Take a look:
Gustin, Benoist, as well as Jessie L. Martin, Carlos Valdes, Jeremy Jordan, John Barrowman, and Victor Garber are scheduled to appear - and sing - in the episode. The villain will be the Music Meister, played by Darren Criss - another Glee veteran.
The Flash's "Duet" episode is scheduled to air March 21 on the CW.
