Walt (Disney) said 'Read the Pooh stories and let me know what you think.' We tried, but the stories just weren't coming through to us. At that time designer Tony Walton was working on Poppins. He was English-born, and he was about our age, so we asked him to give us some insight on the Pooh character. His eyes lit up. 'Winnie the Pooh?', he said. 'I love Winnie the Pooh! Of course I'll help you!' Three hours later, he was still talking about Pooh, inspiring us no end. He explained how he had been a chubby little boy, and had felt very insecure. But Winnie the Pooh was his buddy, because Pooh was pudgy and proud of it. Pooh was probably the only character in the world who exercised to gain weight! Pooh was a wonderful, lovable friend who would never let you down or turn his back on you. Soon, we started to fall in love with Pooh ourselves. Our songs for Winnie the Pooh were truly a love affair, thanks to A.A. Milne and to Tony Walton.

They divorced in 1967 but still remain close chums. Walton married Gen LeRoy in 1991. Daughter Emma Walton's godmother is actress and comedienne Carol Burnett, as well as the prima ballerina, Svetlana Beriosova. Emma's godfather is Vic Oliver. Tony Walton is grandfather to Emma's two children: Sam and Hope. He, Andrews and their daughter have worked several times together professionally. He has illustrated several children books written by Andrews and their daughter.
