Imagine if Milli Vanilli had been classical musicians. One of Japan's most popular musical figures admitted Thursday that someone else secretly wrote his most famous compositions, and he probably faked a hearing disability. Mamoru Samuragochi has been called Japan's Beethoven and was exposed as a fraud by his ghostwriter on Wednesday. “He told me that if I didn’t write songs for him, he’d commit suicide,” Takashi Niigaki said yesterday. The timing couldn't be worse: a Japanese Olympic figure skater was planning to use a Samuragochi song in Sochi.
