‘The Flash’ and ‘Supergirl’ ‘Duet’ Right in Musical Crossover Episode

Move over, LaLa Land. The much-anticipated musical crossover episode of Supergirl and The Flash has officially been scheduled.  The Berlantiverse is getting its song on in at the end of Supergirl‘s March 20 episode and will play out primarily on The Flash the following night.

Entitled “Duet,” The Flash‘s March 21 hour will see both of our heroes in a very new setting after being zapped by the still-to-be-cast Music Meister. In addition to performances by Glee vets Grant Gustin and Melissa Benoist, the episode will also showcase The Flash‘s Jesse L. Martin (“Rent”) and Carlos Valdes (“Once”),  Supergirl‘s Jeremy Jordan (“Newsies”), and Legends of Tomorrow‘s John Barrowman (“Sunset Boulevard”) and Victor Garber (“Sweeney Todd”)—all musical-theater vets.

Unfortunately, that means we won’t get to see Chyler Leigh werk the dance moves she previously showed off in the prom-night number from Not Another Teen Movie. Oh well, there’s always next season!

Supergirl and The Flash air Mondays and Tuesdays respectively, 8/7c, The CW.
