They formed in November 1963 as The Trendsetters, and became The Hedgehoppers the following year. Jonathan King took over their record production in 1965, and added "Anonymous" to their name when they said they were popular in Peterborough, and did not want to change their name completely.
Their major success was the King-produced and -written "It's Good News Week", issued on Decca. This song has also been used as the theme music for "Good News Week", a satirical news-based comedy quiz show on Australian television which ran from 1996 to 2000 and has subsequently been revived in 2008. Four other singles were released by the group before the final line-up dissolved. Lack of further chart activity leaves them labelled as one-hit wonders.
