Spoiler : I am a Japanese. My mother Tokuko Nishikawa (nie Harada), who died in March last year at the age of 98, had listen the concert in New York at the age of 18 on March 12, 1939. I don't know whether she could listen the concert in live concert or through radio program. She wrote about the impression of Jan Kiepura's performance for MAGIC KEY in her diary. It is very impressive for me to be able to listen the performance in Tokyo more than 80 year's after the concert by internet. Thank you.
