Pentatonix Joins Autistic Girl On Stage, Their Rendition Of 'Hallelujah' Will Leave You Speechless

There are performances we hear in our life that truly touch our souls. One moving performance like that was between Irish singing sensation Kaylee and the talented members of the all-star acapella group Pentatonix.

Together, the group shared the stage and sang a rendition of "Hallelujah" by Leonard Cohen that was too beautiful for words. Even the usually boisterous Steve Harvey - a man who always has a joke up his sleeve - was left speechless by the way these six sang.
