Grasshopper is a Hong Kong Cantopop boy group formed in 1985. The band consists of Edmond Chi-Wai So (Chinese：蘇志威), Calvin Yat-Chi Choy (Chinese：蔡一智) and Remus Yat-Kit Choy (Chinese：蔡一傑). Calvin and Remus are brothers and grew up with neighbour Edmond in a poor neighbourhood in Hong Kong. It was Remus who was interested in dancing and singing at the beginning. His mother was his dancing teacher. In order to enter a talent competition, the 16 year old Remus enlisted Calvin and Edmond as his back-up dancers. The act did not make it far in the competition but began to perform as a trio. They later named themselves Grasshopper inspired by their agility and favourite cocktail.
In 1985, the trio auditioned in the Hong Kong New Talent Singing Awards where Anita Mui was one of the judges and its first ever winner.
Due to a black-out during the audition, Anita began to chat with the trio. Soon after, they were invited to perform as back-up dancers/singers for Anita Mui. She acted as their mentor and even visited them at their low cost houses in her limousine. This created a big scene at the housing area.
The trio released their first album in February 1988 and continued to go on tour with Anita Mui. In 2000, Edmond was approached by TVB to star in a series. This started a period where the Grasshopper members pursued their respective solo careers. Contrary to popular belief, the band never was dissolved.
They stopped singing and focused on acting for a few years, but returned to music in 2005 when they opened a few successful concerts. They are best known for their talent and their physical features.
The band currently hold concerts all over the world including in Las Vegas.
Edmond So has 2 daughters, Yumi (born in 1999) and Ina (born in 2007), with his wife, former singer Winnie Lau Siu Wai. The pairs met and began dating in the early 1990s and got married in 1998. This caused anger from fans of Roger Kwok as Winnie was Roger's girlfriend at that time. Roger and Edmond starred in a TVB series together in 2003 called the Greed Mask.
