a navy background which became the image for the World Youth Day 2008. The image is commonly known as Marjorie’s Bird, although Liddy calls it The Day The Holy Spirit Visited Marjorie And Her People, her people being a reference to all Australians. Liddy had never painted before she created this image which was included on the back of the chasubles for the papal Mass. Liddy tells the story of being touched by the Holy Spirit after a day of fishing which provided the inspiration for the image. Official song "Receive the Power", an original song written by Guy Sebastian and Gary Pinto, was chosen in May 2007 as the official anthem for World Youth Day 2008. "Receive the Power" was played extensively throughout the six days of World Youth Day and also in the television coverage which went around the world. Sebastian performed at the concert after the Opening Mass which officially welcomed Pope Benedict XVI to Australia. Sebastian and Paulini also performed both the English and international versions at the Final Mass at Randwick Racecourse on 20 July. An estimated 400,000 people attended the mass. Sebastian and Paulini were invited to perform "Receive The Power" at the Pope's farewell and thank you to volunteers on 21 July. Indulgences The Pope announced that pilgrims at World Youth Day 2008 and those from around the world who pray for the "spiritual goals of this meeting and for its happy outcome" would be able to receive indulgences. In Roman Catholic teaching an indulgence is believed to erase the temporal punishment (time spent in purgatory) which results from sin. Two types of indulgences were available: plenary (full) indulgence – for attendees partial indulgence – for those who pray Controversies around the World Youth Day Public funding Some were concerned regarding the NSW state government's public funding of $129 million and the federal government's funding of $55 million. Some described it as a "promotional event" for the Catholic Church. However the Sydney Chamber of Commerce estimated that World Youth Day would generate $230 million of economic activity and the NSW state government claimed that it would have a direct economic benefit over $150 million. In addition to direct benefits the state government said that the coverage of World Youth Day overseas was worth at least $1 billion. These gains would offset and exceed the government's expenditure on World Youth Day. Use of Randwick
