The series started out with seven celebrities paired with professional Irish dancers. Each week they were given a contemporary Irish rock or pop song (as chosen by producers), to which the professional Irish dancer had to choreograph a traditional Irish dance. They would then dance for the judges, who would give feedback and subsequently award points. The dancers then faced a public vote, with the two couples who received the lowest number of votes having to face the judges again. When the judges revealed the number of points they were awarding, the couple with the lower score were eliminated.
Series One launched in March 2006, in the slot regularly occupied by You're A Star. With a mix of high profile celebrities such as the singer Dana and Olympic Gold Medallist Michael Carruth, as well as relative unknowns, such as Emma O'Driscoll and Suzannae Walshe, the show slowly climbed the ratings and achieved a reported 43% audience share.
