It's 'Star Wars Day' and chances are you've heard the iconic John Williams' 'Star Wars' theme today at least 7,183 times. Here's number 7,184, but this one is worth sitting through all the way to the end.

Vocalist Nick McKaig is known across YouTube as a talented singer who has performed and recorded some very complex and scarily accurate renditions of TV themes such as 'The Muppet Show,' 'Bill Nye the Science Guy' and 'The Simpsons.' This time, he lends his voice(s) to John Williams' most famous movie theme in honor of 'Star Wars Day.'

The most impressive part of McKaig's work is his range. He doesn't just hum or vocalize the main theme-- he breaks down every individual instrument and voice in every song he does from the booming bass drums to the high-reaching trumpets.

It takes more than a great voice to pull off such an impressive, instrument-less feat-- it takes a great ear and precision-like timing to make all of the voices and sounds work in unison to create such a perfect sound. We're not keeping very close tabs on Bobby McFerrin but if we were him, we would be losing sleep over our very career after watching this.

It also offers a very nice break from the endless times we've heard that loud booming song that always come after the "A long, long time ago, in a galaxy far, far away..." today. But McKaig's version, along with the guy playing the same song on the bagpipes while riding a unicycle,  are going to be stuck in our head long after 'Star Wars Day' has passed.
