It was Elgar's Nimrod that was played (listened to it after reading your reply). Thanks!

(I don't know if this is the correct forum section for this post) I just watched the premiere of Homeland season 5 and when Carrie was in the church I recognised the chords played from the organ. The sound very similar to the last part of The Globalist. I couldn't find any other findings of this when googling, but has anyone else noticed this? I guess that must be an old hymn that has inspired Muse for that part of The Globalist. Does anyone know what hymn that is?
