Dalziel & Pascoe

Dalziel and Pascoe was a long running crime series partially based on the books by Reginald Hill about two detectives in Yorkshire. Dalziel is played by Warren Clarke and Dalziel by Colin Buchanan with a very impressive list of one-off guest stars. These are TV recordings. I point that out as I believe most of D&P is available on DVD in the Region 2 part of the world while Episodes 1 - 7 (and 8 - 11 shortly) are available in Region 1 land.
