This must be about Heather Louise McCartney - Linda's eldest - born Heather Louise See. en.wikipedia.org/wiki/Heather_McCartney Paul loved her and her mother so much that he adopted her! Can't you imagine him singing this to Heather in the early 70s at their farm on the Mull of Kintyre! She was truly "Mama's Little Girl"! and he loves her still!
