It's nice to see that Firefly still has the ability to bring joy to the Verse. Here, three castmembers from the CW's The Flash — namely Jesse L. Martin, Carlos Valdes, and Rick Cosnett — came together to sing The Ballad of Serenity in honor of Joss Whedon. Clearly, Whedon can bring even Marvel and DC together.
Martin and company did the performance as a thank you to the Avengers director for donating to their Kickstarter campaign. The group is currently in the process of producing a musical short film called The Letter Carrier, which is set in 1860 and tells the story of a family living in the mountains away from slavery. That Whedon donated likely helped the trio reach and exceed their funding goal.
What better way to say thank you than by singing an homage to one of Whedon's most beloved TV shows?
