Ian Carmichael reprised his television role as Lord Peter in ten radio adaptations for BBC Radio 4 of Sayers's Wimsey novels between 1973 and 1983, all of which have been available on cassette and CD from the BBC Radio Collection. These co-starred Peter Jones as Bunter. In the original series no adaptation was made of the seminal "Gaudy Night", perhaps because the leading character in this novel is Harriet and not Peter; this was corrected in 2005 when a version specially recorded for the BBC Radio Collection was released starring Carmichael and Joanna David. The CD also includes a panel discussion on the novel, the major participants in which are P. D. James and Jill Paton Walsh. "Gaudy Night" was released as an unabridged audio book read by Ian Carmichael in 1993.
