Although born in Hamburg, Germany, Cornelia Moller came to South Africa at the age of 3. She had a huge hit in 1968 in South Africa with 'Picking Up Pebbles'. Cornelia Dahlgren: 'Oxygen is my friend. Without her, you could say I just wouldn't be. My song... our song, that you hear - it’s a relationship. Our conversation. The air and my chest meeting at some half way point in my throat. So, this is what I do. .
