The Wiggles are an Australian children's music group formed in Sydney, New South Wales in 1991. The current members of the group are Anthony Field, Lachlan Gillespie, Simon Pryce and Emma Watkins. The original members were Field, Phillip Wilcher, Murray Cook, Greg Page, and Jeff Fatt. Wilcher left the group after their first album. Page retired in 2006 due to ill health and was replaced by understudy Sam Moran, but returned in 2012, replacing Moran. At the end of 2012, Page, Cook and Fatt retired, although Cook and Fatt retained their shareholding in the group and all three continued to have input into the creative and production aspects of the group.
Field and Fatt were members of the Australian pop band The Cockroaches in the 1980s, and Cook was a member of several bands before meeting Field and Page at Macquarie University, where they were studying to become pre-school teachers. In 1991, Field became inspired to create an album of children's music based upon concepts of early childhood education, and enlisted Cook, Page, and Fatt to assist him. They began touring to promote the album, and became so successful, they quit their teaching jobs to perform full-time. The group augmented their act with animal characters Dorothy the Dinosaur, Henry the Octopus, and Wags the Dog, as well as the character Captain Feathersword, played by Paul Paddick since 1993. They traveled with a small group of dancers, which grew into a larger troupe in their later years. They produced their DVDs, CDs, and television programs independently since their inception. The group's high point came in the early 2000s, after they broke into the American market.
