50 year old David Allen Welsh has been a homeless man living in Vancouver most of his life. He recently learned how to upload his piano playing to YouTube and now we can all enjoy his skills. David says he's never taken a music lesson and that he can't read music. When you watch this video of his piano playing, it may move you to tears.
The Huffington Post reports:

Last Friday, KATU filmed Welsh's playing and the emotional reaction of one listener, James Maynard.

"He started to play, and I choked on my coffee and it started coming out of my nose," Maynard later told ABC News. "I had tears coming to my eyes when I saw his fingers go down one end of the piano to the other."
