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, Emma Watkins, Simon Pryce and Lachlan Gillespie. 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. A school project led to the recording of their first album and tour in 1991. As a result of their background, the group combines music and theories of child development in their videos, television programs, and live shows. Since their inception, other regular characters (Captain Feathersword, Dorothy the Dinosaur, Henry the Octopus, and Wags the Dog) and a troupe called "The Wiggly dancers" have toured with them and appeared in their CDs, DVDs, and television programs.
