This made me laugh. From the Beeb,

They are talking about the new actor who is taking over the lead of Taggart, a crime show set in Scotland.

He [norton] played a butcher suspected of murder and putting his victims in his meat pies. Norton does not consider this a problem. After all, he says, he is probably the only Scottish actor to have been in the series just the once.

Almost every scottish actor has appeared in Taggart at one point or an other. I also saw them filming on location in Kirkintilloch once.
