Movie Pan (2015) certain song?

And although there's a place in this film where this song is specified:

Something's not right - Lilly Allen

but in the movie you can hear a choir sing with the same melody and I can't find it anywhere although this version is much better.

Who has Netflix can see the movie the song starts at 1:00:30.

Did you read the question correctly?

Jep, song, movie, artist, choir everything available.

Ok, of course, that have worked extra for the film
