I had a chance to play that instrument for six days. Hearing German spoken around me made me think of my father, who died in 1960, and whom I hadn't thought much about in recent years. And I remembered what he meant to me. I played "Du, du liegst mir im Herzen" because my father used to sing it to me. So I sat there, thinking of my father, and weeping.
