Some time ago now Paul Martin and his team filmed some "Flogit!” (antiques programme) episodes in Rochester Cathedral. I think they filmed 2 episodes. Each episode includes a visit to a local site of historic interest, one of which was Medway Queen at Gillingham Pier. The other one, featuring Chatham Dockyard, was shown recently.
Although we have not had any notification I think the "Medway Queen" episode is coming up shortly. According to my TV listings this coming Friday’s episode is also from Rochester Cathedral, and not billed as a repeat, so it could be the one with a half time visit to Medway Queen.
