What is the name of the tune played before the national anthems in International rugby matches?

Question

Before they play a match in International rugby, a song is played before the anthems. It's always played, sounds quite classical and I have no idea what it is. Help?

Answer 1

The song is "World in Union", adopted as the official music for international rugby and the World Cup.  It sounds classical because it's based on Jupiter, as part of the Planets Suite by Holst.
