"I gave everything to it I was able to give. What I have here accomplished, I will never achieve again." So said child prodigy, virtuoso pianist, intellectual, conductor and composer Camille Saint-Saëns about his wildly successful 1873 ‘Organ Symphony’. Famously featured in the 1995 porcine Disney film Babe, it’s still immensely popular today. But where did it come from? What was Saint-Saëns trying to achieve and how influenced was he by his Parisian contemporaries? With organist Anna Lapwood on the thrill of playing ‘that chord’ in the Royal Albert Hall at the BBC Proms. Producer: Ruth Thomson
