Great day for me getting inside the house of professional singer and he teach me how to sing a song as beginning. Kru Book seems to be happy all the time his singing. He makes people smile and feel inner when listening his songs. When I got his place, he's singing with the band. Then I followed his singing class that he also taught the foreigner before we have talked. From his honor experiences and works, he becomes "Guru" that people realize how he's wonderful.
