Menzel was excited that there was a little boy was at her concert, she said in the video.

“It was really cool to be able to see her point him out and give him a moment in the spotlight because it was something that was 'unusual,'” Rivera-Sanchez said.

Rivera-Sanchez commended Chacko’s confidence and vocal power at such a young age.
