Tributes have been paid to Rob Grant, the comedy writer best known as the co-creator of long running hit sitcom Red Dwarf. Grant was also one of the main writers on Spitting IMage for many years, writing regularly with Doug Naylor.The news was broken by the Red Dwarf fan site, Ganymede and Titan. (note - at the time of writing the site has gone down due, presumably, to so many fans trying to find out more details).Craig Charles, who played Lister posted on X: "Earlier today I was informed of the passing of @realrobgrant .i am in total shock.He was one of the funniest people I’ve ever met.
