In November 2006, the Rolling Stones' 'A Bigger Bang' tour was declared the highest-grossing tour of all time, earning $437 million. In December 2009, a campaign was launched on Facebook by Jon and Tracy Morter, from South Woodham Ferrers, which generated publicity in the UK and took the 1992 Rage Against the Machine track "Killing in the Name" to the Christmas Number One slot in the UK Singles Chart, which had been occupied the four consecutive years from 2005 by winners from the TV show The X Factor.
