Two cast members of HamiltonBroadway's biggest show, paid homage to a classic PBS kids' show yesterday (June 23), posting a brief cover of the Arthur theme song online.

Anthony Ramos (who plays both John Laurens and Philip Hamilton in the production) and Jasmine Cephas Jones (Peggy Schuyler and Maria Reynolds) uploaded a short video to Instagram of the two singing "Believe in Yourself," which was originally recorded by Ziggy Marley and the Melody Makers for the show. Their reworked version is harmonized to high heaven but maintains the track's original melody, appealing to Arthur fans and theater nerds alike.

Jones later posted on Twitter that her "childhood is legit freaking out," after the show's account retweeted their video.

If you can believe it, this isn't the first time the theme song has received a musical update. Back in 2014, Chance The Rapper recorded his own version of the track, and it featured guest appearances from Wyclef Jean, Jessie Ware, Elle Varner, Francis and the Lights, Allen Kane, the O’my’s, Peter Cottontail and Donnie Trumpet. Check out Chance's version below.

The cast of Hamilton is undergoing a major overhaul at the moment, as three of the show's lead actors are gearing up to part ways with the production within the next few weeks. The show's creator and star, Lin-Manuel Miranda (who portrays the titular character) will take his final bow on July 9, along with Philippa Soo (who plays Hamilton's wife Elizabeth Schuyler) and Leslie Odom Jr. (Aaron Burr), according to Vulture.

But for fans mourning the fact that they'll never see Hamilton with its original cast, there's hope for you yet...sort of. According to Miranda, two performances of the historic show will be taped before July 9, ensuring the OBC's version will forever be preserved on video.

“We don’t know what we’re doing with that footage,” he told fans via Periscope. “We’re going to film it as best we can in the highest quality thing that exists, and then we’re going to put it away. I want you to rest easy knowing that I’m leaving, Pippa’s leaving, Leslie’s leaving, but this thing is going to exist. We’ve been working it for months to make it happen.”
