Keeling is the Animal Director and co-founder of Monkey World in Dorset, and here he tells the story of his friendship with Amy, an orang-utan abandoned by her mother, who he rescued from the private menagerie of music impressario Gordon Mills.
Keeling and Amy were involved in a horrific car crash, and Amy saved Keeling's life.
He then joined forces with Jim Cronin, and together they built Monkey World, which has 800,000 visitors a year.
