You may have already seen these little darlings perform. They are the Cactus Cuties. The only way you can be a member is to have a name like Kitten, Madeline, Baylee and Blaire.
They got their big national debut after performing at a Texas Tech basketball game. Their performance was then posted on YouTube and garnered MUCH attention.

But, by and far (at least for me, because it is one of my favorite songs) one of their best performances was their singing of the Battle Hymn of the Republic.
