A man sat at a metro station in Washington, DC and started to play the violin; it was a cold January morning. He played six Bach pieces for about 45 minutes. During that time, since it was rush hour, it was calculated that thousands of people went through the station, most of them on their way to work.
This reminded me so much of the many buskers that line the Buchanan Street Mall in Glasgow during World's week. I always stop to listen, contribute to their coffers and scan the listeners stationed nearby - always with admiration for their attentiveness.... Merry Christmas
