Grant Gustin Dips Melissa Benoist in New Poster for The Flash/Supergirl Musical Episode

A brand new poster for the upcoming musical episode of The Flash has been released. The poster features Grant Gustin dipping Supergirl star, Melissa Benoist.

Melissa, Jeremy Jordan, Dave Harewood and Chris Wood are all set to appear in the musical episode. The story, which features Darren Criss as The Music Meister, will kick off towards the end of Supergirl’s episode this coming Monday, March 20.

It will then pick up steam in The Flash’s episode on Tuesday, March 21. I am loving all the promo for this episode, but I need footage of them singing!
