Maybe It's Because He's A Londoner?

...that he sings of her
whenever he's here...

Ladies and Gentlemen: Meet "that 'Streets of London' guy" from Fürth - Richard Smerin by name. He has over two hundred original songs to his credit and proves it on his web page http://www.richardsmerin.com, it's just that he chooses to stick to his trademark one when he's playing downtown Nuremberg's pedestrian zone. I'm glad I finally found out his name last spring - he's also got sixteen CDs (as of May 2016) on sale, you just have to ask! Well, sometimes you don't ;)
