Adams says, “I did have something of a guilt thing about reading English. I thought I should have done something useful and challenging. But while I was whingeing, I also relished the chance not to do very much.” Even his essays were full of jokes. “If I had known then what I know now, I would have done biology or zoology. At the time I had no idea that was an interesting subject, but now I think it is the most interesting subject in the world.”

Other contemporaries included the lawyer and TV present-er Clive Anderson. The culture secretary Chris Smith was president of the union. Adams used to do warm-up routines for debates, but not because of any political interest: “I was just looking for anywhere I could do gags. It is very strange seeing these people dotted around the public landscape now. My contemporaries are starting to win lifetime achievement awards, which obviously makes one feel nervous.”

After university, Adams got the chance to work with one of his heroes. Python member Graham Chapman had been impressed by some Footlights sketches and had made contact. When Adams went to see him, he was asked, much to his delight, to help out with a script Chapman had to finish that afternoon. “We ended up working together for about a year. Mostly on a prospective TV series which never made it beyond the pilot.” Chapman at this time was “sucking down a couple of bottles of gin every day, which obviously gets in the way a bit.” But Adams believes he was enormously talented. “He was naturally part of a team and needed other people’s discipline to enable his brilliance to work. His strength was flinging something into the mix that would turn it all upside down.”

After he split up with Chapman, Adams’s career stalled badly. He continued to write sketches but was not making anything like a living. “It turned out I wasn’t terribly good at writing sketches. I could never write to order, and couldn’t really do topical stuff. But occasionally I’d come out with something terrific from left field.”

Geoffrey Perkins, head of comedy at BBC television, was the producer of the radio version of Hitchhiker. He remembers first coming across Adams when he directed a Footlights show. “He was being heckled by a cast member, and then he fell into a chair. I next came across him when he was trying to write sketches for the radio show Weekending, then regarded as the big training ground for writers. Douglas was one of those writers who honourably failed to get anywhere with Weekending. It put a premium on people who could write things that lasted thirty seconds, and Douglas was incapable of writing a single sentence that lasted less than thirty seconds.”
