Argh! I am going mental! It's not credited anywhere, not at the end titles, not on IMDB.
It's so familiar. Is it Händel's MEssiah? JOhannes Passion by Bach?
Help!!

It's Handel's coronation anthem 'Zadok the Priest'; but I expect you know that by now (I see that your question was posted two-and-a-half years ago!!).
shareIt's a little late to reply to this question, but the music IS listed in the end titles. It is Händel's Coronation Anthem "Zadok the Priest." Throughout the film the long orchestral introduction to the choral part is played, building up the suspense, perhaps only to those familiar with the piece, but the voices enter only once during the film, when Dean first introduces himself as Alex, as if to announce that his imposture was successful.
The anthem has been played at British coronations for centuries. There is a long introduction, and then the chorus blares out
Zadok the Priest
And Nathan the Prophet
Anointed Solomon king;
And all the people rejoiced and said
God save the king!
Long live the king!
May the king live forever!
Alleluia, Amen.
