Here is the story of his ill-fated solo cycling tour of Europe in the summer of 1939.
And here is his one published foray into fiction (to the best of my knowledge), a story written after the War and looking back at one hot and steamy corner of it.
Finally, here is a two part interview he did, I'd guess in the early '90s. I believe it was for a collection of interviews his interlocutor was making on the subject of inspiration, and he begins by talking about that subject, but covers a lot of ground by the end, from pottery, to Quaker meetings, to healing, to the way he became a schoolteacher. This is characteristic of the way he talked in later life, before he declined into dementia, and I'm very glad to have it.
