The CW has already aired its big four-show DC crossover for this season, but we’ve still got one other team-up to look forward to as Melissa Benoist’s Supergirl reunited with Grant Gustin’s Flash for a two-part musical crossover, which will pit the heroes against Music Meister.
Thanks to EW, we now have details on who’ll be flexing their vocal cords in the crossover, with the site reporting that Benoist, Gustin, Jesse L. Martin, Victor Garber, Carlos Valdes, Jeremy Jordan, and John Barrowman will all be delivering musical performances in The Flash instalment, entitled ‘Duet’ (much like the Invasion! event, the crossover will begin at the very end of the Supergirl episode). Supergirl stars David Harewood and Chris Wood will also guest star in The Flash episode, albeit in non-singing roles.
The crossover is set to air on March 20th and March 21st.
