Does anyone know the rousing music they played over the loudspeakers at the start of every rugby match during the last rugby world cup?

is it "world in union"

It's a re-worded version of I Vow to Thee My Country

as sung by our cath http://www.youtube.com/watch?v=ftopjl_3h6k

The tune is Jupiter by Holst.
He later added words to make it "I vow to thee my country"
These were later basterdised into "World in Union" for the 1991 Rugby World Cup.

3:07 onwards....

and I cant think of a better reason to basterdise! Original is a great peice of music, "I vow" is a great hym and "World in Union" is a great anthem.
