Beautiful. Whoever arranged it did an awesome job of avoiding banal cadences.
I agree. I usually cringe at the way the Anthem is arranged (especially for SATB), but whoever arranged this for five-part girls did an exceptional job.
Those who have never been a member of a choir might not have noticed this, but the girls started off right on pitch, without any use of a pitchpipe (as far as I could see) — something not easy to do. They also stayed right in key and did not rush the tempo. An excellent, excellent performance!
