The folk singer Leonard Cohen from Canada has performed for the first time in the United States in 15 years. He cracked a lot of jokes on his age and also on the various themes that he used for his songs. It is in fact the first performance that he has given since his becoming a monk. The musical show was held at one of the best places in New York. The 74-year-old Canadian singer was dressed in a trendy coat and hat. Cohen has been on tour since May, performing in various countries like Australia, Canada and so on. Cohen was inducted into the Rock and Roll Hall of Fame in 2008.
