Task: Question Answering
Input (English): Passage: In mid-2012, The Wiggles announced that Page, Fatt, and Cook would be retiring from touring with the group; Emma Watkins, the first female member of The Wiggles, replaced Page, Lachlan Gillespie replaced Fatt, and Simon Pryce, who was initially supposed to replace Page in August, replaced Cook.  Anthony Field remained in the group because he found it too difficult to give up and because he still had a passion for educating children.  According to Paul Field, his brother staying in the band "was a vital decision to placate American, British and Canadian business partners".  Page, Fatt, and Cook remained involved with the creative and production aspects of the group.  Fatt and Cook had been talking about quitting touring for many years; Cook announced his intention to retire first, citing a desire to spend more time with his family, and then Fatt announced his own retirement shortly thereafter.  Page, who was still struggling with his health issues and had stated that his interest was in working with the group's original line-up, was subsequently asked to extend his stay until the end of the year so he would leave alongside Cook and Fatt, to which he agreed.  Cook reported that the original members were confident that the new group would be accepted by the fans because they passed on their founding concepts of early childhood education to Watkins, Gillespie, and Pryce.  The new members, like Moran, who was not approached to return, were salaried employees.The group, for their farewell tour, visited 8 countries and 141 cities, for a total of almost 250 shows in over 200 days for 640,000 people.  Watkins, Gillespie, and Pryce wore "In Training" T-shirts, and debuted the song "Do the Propeller!" during these concerts.  The final televised performance of the original band members, along with the new members, was on 22 December 2012, during the annual Carols in the Domain in Sydney. Their final performance, after over 7000 shows over the years, was on 23 December at the Sydney Entertainment Centre.Also by 2012, The Wiggles performed to audiences whose parents attended their shows in their early years, and they were hiring performers who were part of their audience as young children.  The Wiggles began airing a show on Sirius XM satellite radio in late 2012, featuring the original members and their replacements, and stories and games for young listeners.  In December, the group auctioned their famous "Big Red Car" (called the "iconic Volkswagen Beetle Cabriolet") for charity for almost A$36,000 on the auction site eBay.  The money was donated to the Melbourne-based charity SIDS and Kids.
