got a feeling they used it or something similar in Kingdom. the music is called Thaxted, by Gustav Holst, he adapted part of his "Jupiter" from the Planets Suite...Manfred Mann's earth band also used it in their song "Joy Bringer"
I was kind of right with the momentous occaision thing, 'It was featured in a Top Gear episode where Jeremy Clarkson drives a Land Rover Discovery up the tallest mountain in Scotland.' I saw that episode a few days ago.
The music of Thaxted is often used in a number of common Christian hymns. So I knew the tune from other hymns aswell. But can anyone elighten me as to which hymns have the same tune?
