Awesome story. A former boss of mine spent a year posted in Prague on assignment. He said it is as common there for the Czechs to get out their instruments and hold a jam session as it is for Japanese to go out for Karaoke or Americans to go out to dinner.
As a result, the average level of playing musical instruments is rather good in the Czech Republic, the average level of singing is rather good in Japan and the average level of eating is rather good in America.
