They're cute, they're good.
I wish I sang half that well & had a quarter of their moxie / self-esteem.
But I still think that the National Anthem is not (or at least, should not be) a performance; it's a singalong by everyone attending the event, a reaffirmation of united purpose. The range of the song is outside the range of most people - that's why we need a group to sing it.
Sort of a mini melting pot, those beautiful voices (soprano) with the gruff/hoarse veteran (bass) with the gal who sings in church choir (alto) with the guy who only sings in the shower (tenor) 'cause he really can't carry a tune. And it comes out just like America - lumpy in places, maybe a little rough, but good.
