Just been re-reading bumpa Christmas 2000AD prog 2012 from December.
In the new horror based strip Absalom, the titelular protagonist refers to a number of coleagues he has worked with over the years, all from populare culture that have dabbled in the paranormal.
Amongst these are Inspector Trout from the Abominable Dr. Phibes, Inspector Calhoun from Death Line, Jack Reagon of The Sweeny, and Inspector Barlow from Z Cars and affiliated storys.
Finaly came "That Irish git who was involved in that Zombie mess up in Manchester" was none other than the un-named police officer played by Arthur Kennedy in Living Dead at the Manchester Morgue.
Love stuff like that!
