With an almost national audience, the show became inclusive of its increased viewership by making a bigger role out of specially invited viewer performances. Many of these were children who sang songs or performed dance routines. Chris Tarrant, now producer as well as presenter, found most of these contributions to be of little value, until he came across a unique act by a five-year-old boy, Matthew Butler. Encouraged by his "Tiswas"-obsessed mother, Butler auditioned for the series wearing a rabbit costume and sang the song "Bright Eyes" made famous by the animated film "Watership Down", although his own singing ability was rather poor. Tarrant found this so amusing that he arranged for him to appear on the following "Tiswas", as well as many subsequent editions.
