Many are still mourning the news of Mexican icon Juan Gabriel's death, whose passing has created a void in the Latin American music scene.
Anthony had previously covered Gabriel's song on his 2010 album, "Iconos," but on Sunday night, he was so overcome with emotion he found it hard to perform.
During the electrifying performance, Anthony paused several times attempting to hold back his tears. At one point, he even asked for help from the audience, prompting them to sing along.
The singers also collaborated on "Yo Te Recuerdo" for Gabriel's album, "Los Dúo 2."
It's not hard to see why Anthony was moved to tears, it's clear the love and respect these two had for one another ran deep.
