Eric Kwok may not be a household name, but if you've heard any Cantopop since the late '90s, you'd recognise a few of his tunes. The list of artists who have sung Kwok's songs reads like a venerable who's who––Leon Lai, Jacky Cheung, Cass Phang, Gigi Leung, Miriam Yeung, and Kay Tse––and "Happy Ferris Wheel" for Eason Chan even turned Kwok into a celebrity among Cantopop fans.
