Does anyone know what the song is called at the beginning of the rugby world cup?

Question

I love the classical song at the beginning of the rugby world cup!!

Answer 1

It is called The World In Union and is the Official theme for The Rugby World Cup and has been for years. Kiri Te Kanawa has recorded a version and so has Bryn Terfel.

Answer 2

I vow to thee my country???

Answer 3

I clicked on to say World in Union etc then noticed what the first answerer had said.  I am sure it is World in Union but the words were put to the tune of I Vow to Thee my Country.  So I think both answer 1 and 2 are correct.
