Grant and Naylor wrote the first six series together (using the pseudonym Grant Naylor on the first two novels and later as the name of their production company, although never on the episodes themselves) before Grant left in 1996, leaving Naylor to write the final two with a group of new writers, notably including Paul Alexander and actor Robert Llewellyn.
For the most part, Ed Bye produced and directed the series. He left before Series V due to a scheduling clash (he ending up directing a series starring his wife, Ruby Wax), and Juliet May took over as director, but she parted ways with Grant and Naylor partway through the series for personal and professional reasons. Grant and Naylor took over direction of the series, in addition to writing and producing. Series VI was directed by Andy De Emmony, with Bye returning for the final two series.
Series I, II and III were made by Paul Jackson Productions, with subsequent series produced by the writers' own company Grant Naylor Productions, all for BBC North; all eight series were broadcast on BBC2. At the beginning of Series IV, production moved from the BBC's Manchester studios to Shepperton.
The theme tune and incidental music were written and performed by Howard Goodall, with the distinctive vocals on the theme tune courtesy of Jenna Russell. Goodall also wrote music for the show's various songs, including "Tongue Tied", with lyrics written by Grant and Naylor, which Danny John-Jules re-orchestrated and released as a Top 20 single. Craig Charles wrote, performed and sang "Cash" — from the episode "Timeslides" — with his band. Goodall's own voice can be heard in the version of the song "High Noon" in "Queeg" (Series II), and in the "Rimmer Munchkin Song" in "Blue" (Series VII). Chris Barrie purports to have been upset by not being invited to sing this song himself (Back from the Dead, series VII DVD); Howard Goodall, however, insists that Barrie was asked but turned the invitation down (Howard Goodall, Settling the Score, series VI DVD).
