"Edge and Paul McCartney - september 4, 2004 - Dublin - BARRETSTOWN'S 10TH ANNIVERSARY GALA BALL - Barretstown celebrated helping 10,000 kids in 10 years with a glittering gala ball. Paul McCartney, Heather Mills and U2's The Edge joined a host of top socialites to mark the 10th birthday with Hollywood actor Paul Newman, who founded the camp for children with cancer and other serious illnesses. MC for the night was Father Ted's Ardal O'Hanlon and the guests dined and danced in a spectacular Kuam marquee in the grounds of Barretstown Castle, Ballymore Eustace, Co Kildare. The highlight of the night was when McCartney joined The Edge on stage to sing a duet of Peggy Sue while McCartney played the specially-commissioned Barretstown guitar. The guitar, made by Mark Nicol of County Wexford in the shape of the charity's castle logo, was snapped up by Cork art dealer Theo Waddington for a cool E55,000. Other items in the auction, led by Nick Nugent of Goffs, included a corporate package to see Manchester United play Liverpool at Old Trafford, a place on the Barretstown Challenge Trek to Brazil and a Golfing package to Myrtle Beach, South Carolina. Barretstown needs to raise E4 million each year to fund its programmes of challenges, activities and fun which aid in the recovery of sick children from across Europe. The star-studded occasion raised E440,000 for the charity on the night.
