The fantastic keyboardists in my youth band wrote a variation of Agnus Dei for the introduction of my church's countdown party for 2007-2008, thought to share here. The song was played over minor chords, building up with the electric guitar playing the melody at the end, and ending on a climax. Perhaps some of you might like to use it for your church events!
There's alot more to this song - some percussionists did an item, followed by the band playing a medley comprising Alive Overture and some other instrumental songs. The worship leader then comes up on stage with Agnus Dei at the end. Hope to get approval to put the video up on youtube for you guys to have a look! (tho i admit its unlikely)
