Singing "Leaving on a Jet Plane," the father and son duo, Jim Allen and son Sasha who are Newtown natives harmonized their way onto the blind audition segment of NBC's "The Voice," according to nbc.com.

Their perfectly blended harmonies brought down the house during Tuesday's episode as both Kelly Clarkson and Ariana Grande pushed the button to select the father-son duo for their team.

The Voice Facebook page explains that during the blind auditions, the coaches hear the artists perform but don't see them, so their decisions are based on their voice and not their looks.

If the coach is impressed with their voice(s) and wants them on their team, they push a button, and the artist's chair swivels so the coach can see what they look like. The current coaches for Season 21 include Kelly Clarkson, John Legend, Blake Shelton, and Ariana Grande.

Kelly and Ariana pushed their buttons simultaneously, which meant the contestant got to choose which team they would like to join, and Ariana Grande got the call. The show's format features four stages of competition: Blind Auditions, Battle Rounds, Knockouts, and Live Performances.

The Voice is a much more involved talent show than America's Got Talent, which is also on NBC. Judges Simon Cowell, Howie Mandel, Sofia Vergara, and Heidi Klum are faced with the task of choosing the most talented performer(s) who have won the honor of being a contestant. The talent ranges from singers, dancers, comedians, contortionists, impressionists, magicians, ventriloquists, and hopeful stars, all vying to win America's hearts and a $1 million prize.

If I could offer just one comment about the audience during the Newtown father-son duo's performance on The Voice. You never clap along to a song like "Leaving On a Jet Plane." NEVER!
