Nick McKaig Sings 'You're A Mean One, Mr Grinch' In Festive A Capella YouTube Cover (VIDEO)

The Christmas trees are already out, and the festive wreaths are all a-glitter, so it should come as no surprise that holiday tunes have already started to flood the airwaves and, of course, YouTube.

YouTube's Nick McKaig, the a cappella one-man extraordinaire, is kicking off the season with a rendition of the beloved childhood song "You're a Mean One, Mr. Grinch." The song, a Christmas staple and theme from the animated Dr. Seuss classic, shows off what Mashable calls McKaig's "vocal wizardry," as he combines lots of holiday cheer with a cheeky, hot chocolate-y baritone.

McKaig is no stranger to YouTube success. In February, he shot to the spotlight after creating a layered solo version of "The Simpsons" theme song (complete with 30 different voices). According to McKaig, the song was played during the ending credits of Episode 15 during the iconic TV show's 23rd season.

In May, McKaig made headlines after he recorded his own take of the famous "Star Wars" theme, mimicking the entire symphony orchestra with just his voice, the Daily Mail notes.
