The line was hellishly long, and the interior of the church (yes, this event was held in a church) was hellishly hot, but once everybody was inside, it started up promptly. I had the privelege of meeting up with the lovely obopolsk and the equally lovely ofrabjousday, who has already posted what she managed to capture on video. Lacking a transcript, however, I'm going to cut to the chase. After reading a segment from Anansi Boys, Neil said he'd start taking the questions. I raised my hand, not expecting to be called on since there were in excess of 500 people in attendance, but before I knew it he'd pointed at me. So, I stood up and said the same thing I'd said to Terry, only I added, "Terry said he couldn't remember what it was that the two of you had decided they were doing in the South Downs, so I thought maybe you might."
Neil proceeded to go off on an explanation that the first time they'd ever discussed a sequel was back around the time Good Omens itself was first published, and that said conversation had happened at some convention where the two of them were sharing a hotel room to save money (at the time, neither was as successful as they are now). They'd been drinking down at the hotel bar, but Terry went up to bed first, and when Neil finally came back to the room, he was trying to be quiet and find his way in the dark. At this point, Terry, apparently awake, asked if his parents knew he was out and about at this hour. From there, they proceeded to have one of those bleary, early-morning conversations that resulted in the whole potential-sequel concept as the Second Coming, with Jesus arriving in a silver plane with angelic secret service agents, and getting lost in Times Square, etc. He said that this sequel idea corresponded with their then-worldview, ca. 1990, but things are of course very different now. The conversation that he and Terry had earlier this year established that, well, the political climate is a lot different now, and if they ever write a sequel, it will be drastically different from the original concept.
And then, quite simply, he ended the ramble with, "Well, what they're doing on the South Downs is sharing a cottage."
