Bobby Ball

Robert Harper (Bobby Ball) and Thomas Derbyshire (Tommy Cannon) were both born in Oldham. They met in the early 1960s while working as welders in the same factory. Becoming friends, they formed a club act known as "Bobby and Stevie Rhythm", which became the Sherrell Brothers, then The Harper Brothers. Initially they were a vocal duo, but over time started to introduce more comedy into their act. They turned professional in the late 1960s, and eventually changed their name to Cannon and Ball.

Their first TV appearance was on "Opportunity Knocks" in 1968, where they came in last. Other early TV work included appearances on The Wheeltappers and Shunters Social Club (1974) during the 1970s. However, during this time their work remained predominantly in clubs and theaters. Their last TV series was in 1991, by which time tastes had changed and they were not as popular on TV. They continued their theatre summer seasons and pantomimes, where they still drew large audiences. Guest appearances on television continued.

Although things seemed to be going well in the 1980s, things off-stage were darker. Over the years they had gradually estranged to the extent that they no longer spoke to one another except when work demanded. Bobby was drinking heavily, womanizing, and had gained a reputation for violence. In 1986, Ball became a Christian, as did Cannon in 1992. During the 1990s and 2000s, the duo continued working, with theatre tours, summer shows, pantomimes and TV appearances keeping them busy. They performed regular Christian concerts and "evening with..." shows where they spoke about their lives and faith.
