Is it just amazingly similar melody in the The Bridge (Bron/Broen) series intro or simple the copy of Led Zeppelin's No Quarter? I have tried to find out any credits in regard to this, but it was unsuccessfully. The only info I found, that it's Choir of Young Believers performance, called Hollow Talk. ttps://youtu.be/0A1r9Jk9UC8 Just wondered, Is there everything OK here with the copyright here?
