The man’s talents went viral after Roslyn Polard happened upon him tickling the ivories one afternoon in the city's Churchill Square.
“I had to stop and turn around and go back, because it was so beautiful,” she said.
At first, she said, she felt like she might be intruding, since he was playing alone. Polard approached the musician, who she took to be homeless, and asked permission to film him. He agreed, and told her he was already on YouTube.
A quick search of YouTube revealed two more videos that appear to show the same man playing pianos around the city on Aug. 20, and then again a couple weeks later.
