From the video’s YouTube description:
Kindergarteners from Mr. Avina’s class perform Madonna’s “Vogue” for their culmination. No one can strike a pose quite like kindergarteners can!

The parents adored it. You know, these kids come into school singing songs like “I’m Sexy and I Know It,” so you know they are very capable of learning pop songs. By the end of the year, the nursery rhyme kiddie songs become a bit mind-numbing, so I wanted to teach them a pop song that I loved (and this was the result). When your expectations are high, your kids meet them.
