DANISH: Radiovagabond.dk   On my last night in Washington D.C. I was in the area of Union Station. Here I talked to an afro-American street musician. He calls himself "Unknown Pianist Number 100", and used to be homeless. He had a lot to share and that shows another side of the American capital.       LINKS: Sponsor Hotels25.com  See pictures on TheRadiovagabond.com Follow The Radio Vagabond on Facebook, Twitter, Instagram, and YouTube.
