All the children had to wear a gas mask in case of a gas attack by the Germans. They tried to make the masks like Mickey Mouse faces so the children would like them. But I didn't. They had big ears on them.

And then I think they asked me to work on Wish You Were Here, which was the next album coming up. And I didn't do anything for a long time. I had other projects, and I didn't get around to doing anything for a bit.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
