We don’t know much about Marshall, the upcoming biopic about the historic life of Supreme Court justice Thurgood Marshall, but star Josh Gad just shared an incredible behind-the-scenes video from set!

In the clip, which Gad posted to his Facebook page on Thursday, the Frozen star teams up with co-stars Sterling K. Brown and Chadwick Boseman, who plays Marshall, to sing a little old-school “Motownphilly.”

The three are practically pitch-perfect in their harmonies on the iconic Boyz II Men track, and Gad and Brown's period costumes have us longing for the three to team up as some kind of barbershop trio!

For now, we’ll just have to tide ourselves over with Gad’s Ben Franklin-centric spinoff of the hit Broadway show, Hamilton, which he showed off on his Instagram page on Thursday.
