Definitely not a masterpiece - it is extremely easy for choral composers to pile sevenths and ninths on a chord to give their music a fuller sound, the real challenge is for the choirs singing it - but this is a very 'nice' piece which I enjoyed. Musically, it was the highlight of an extremely undistinguished musical selection at the Royal Wedding.
Yes...I watched it. I had a day off on Friday and nothing better to do. So sue my anti-monarchist ass.
