In Korean they're singing "Papa Song has freed us." (Papa Song is, if you remember, the name of the mascot of the fast food chain)

Me too, unfortunately I haven't seen this anywhere as its own song..

Thank you so much, such a wonderful piece!

Thank you!!!

The scene following this clip is the single most horrible thing I have ever seen in a work of fiction.

Is there an extended version of this choir track ?
