Merton is a Colorado resident who has gained a good amount of Internet celebrity for the spontaneous songs he plays for random people he meets on chatroulette.com. But he's not just an online phenomenon. In fact, he frequently takes his show on the road, literally, by playing to passersby on the 16th Street Mall in downtown Denver, which is where we caught up with him.

Says Merton about his spontaneous performances on the Mall:

I don't play on any specific nights; usually the whim just strikes me and I head to Denver with little notice. It's entirely possible that I won't even get down there again before they take the pianos away at the end of this month.

So you may be out of luck if you want to see Merton on the Mall. However, he says he's planning to release the fifth video of his Chatroulette performance on August 10 on his YouTube channel. Finally, Denver Open Media will air a show about Merton soon, so keep your eyes peeled for that.

...And here's a famous (by Internet standards, anyway) video of Merton, which, as of right now, has received 6.2 million views on YouTube:
