Former BEATLE Sir Paul McCartney has paid $2.8 million (GBP1.6 million) to a landmine charity after pulling out of its fundraising concert causing the event's subsequent cancellation. MCCartney was supposed to attend October's (06) Los Angeles gig for landmine charity Adopt-A-Landmine with wife Heather Mills. But due to their current estrangement and ongoing divorce proceedings, MCCartney decided not to go through with his appearance, even though he was scheduled to be the biggest attraction at the fundraiser. Both MCCartney and Mills are sole patrons of Adopt-A-Landmine, with Mills being the founding patron. Last year (05) the singer helped raise a massive $3.06 million (GBP1.7 million) for Mills' charity, which supports the United Nations' efforts to remove landmines across the world. However, in a statement MCCartney says, "While I continue to be committed to Adopt-A-Minefield and its critical mission, given the current circumstances, I will not be able to attend the gala this year." Other stars, including Michael Douglas, Jack Nicholson and Orlando Bloom, have already reportedly paid $900 (GBP500) for tickets to see MCCartney perform at the event, which is now cancelled.
