He blew Menzel and the audience away as he belted out the Frozen song.

“We were all looking at each other, just stunned," actor Jacob Rivera-Sanchez, who recorded the moment, told InsideEdition.com. "We knew he would sing the song but we didn’t know he would sing the song this well."

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.

Once Menzel realized just how good Chacko’s chops were, she called for an encore. Chacko even made sure to take a bow after his performance.
