Re: Officially no series 8 in 2013
Except when there are three. Series one had two credited executive producers (Gardner and Mal Young), as did series five and six (Willis and Piers Wenger). Phil Collinson was also credited as an executive producer on the seven 2007/2008 episodes for which he didn't receive producer credit, a reflection of the overlap in his actual role.
