Mayumi Yamamoto, known as Cindy (b. May 1958 - d. Dec. 2001) was a Japanese R&B singer-songwriter and composer, perhaps best known for composing some of Miho Nakayama's biggest hit songs. She worked with many Japanese Fusion artists throughout the '80s, and even had Stevie Wonder produce her debut album. She released 3 original albums and 1 best selection album over the course of 17 years before succumbing to cancer in December 2001.
