The backstory is that the man who wrote "76 Trombones", Meredith Wilson, went to our church, Westwood Hills
Keep in mind that this is a "Barbershop Quartet" type of Chorus. This is perhaps the most amazing performance with large vocal group ever seen. Be sure to watch to the end… some amazing stage tricks with such a large group, too. The choral work is amazingly crisp and words so clear for a group this size. The choreography is really great too. Good surprise ending too.
In Anaheim July 4th, 2009, a performance by the Ambassadors of Harmony from St. Charles (Metropolitan, St. Louis) Missouri. They scored a 100 out of a 100 for this and probably would have been given more if that was possible.
No chorus had ever scored 100 in the history of Barbershop since 1938.
