Leg up Paul McCartney has been Christmas shopping in London. He bought Heather a new artificial leg, which he had wrapped, before taking it home and hiding it in a cupboard. However, Heather discovered the present only a couple of days later and unwrapped it. She liked the new leg, but was worried she'd spoiled the surprise of her Christmas present. "Relax", said Paul, "that was just your stocking filler."
