Battle Of The Choirs: Mary Did You Know?

Here's two different choirs performing the exact same arrangement of "Mary Did You Know?" One is a black youth choir. The other is an older white choir. Notice the layers and layers of cultural communication that defines each choir: location, attire, phrasing, instrumentation. It's a credit to the composers and arrangers of this song that it could fine a place in such different contexts.

Here's a fun experiment: start the lower video and then at :45 start the top video. It's a mashup! If only the tempos were the same, it would work for the entire tune.
