In spite of the times he’d butted heads with American authority, Captain America remains a pretty patriotic dude. That is on full display in a promo video for Captain America: Civil War featuring a rousing rendition of “Battle Hymn of the Republic” by the Marvel film’s cast.

Chris Evans speaks about Cap’s heroism while Robert Downey Jr., Anthony Mackie, Chadwick Boseman, and Elizabeth Olsen hum and sing the tune, which of course is an American Civil War-era song.

Oh, and Sebastian Stan is there too. See if you can keep from laughing at his presence in this video.
