This info. from another board:
"Professional canal boater Alan Jones reported some year's back: "Chocolate Charlie (Atkins) told me that he was the skipper of the 'Flower of Gloster' for all the series. The narrow boat was the 'Jupiter' which was built of wood by Woods in 1934 as a prototype for what became the Star class and was number 56 in the GU fleet. (See 'The George & The Mary' by Alan H. Faulkner.) Charlie said the boat, hired from its then owner, was not in good condition and he was always afraid it would sink at any time.
"Grenada TV employed a young Oxford graduate to oversee the education of the young actors during the voyage and the filming. She gave a fascinating talk about it to Worsley Cruising Club"
THE FLOWER OF GLOSTER (1967)
"The first drama series to be filmed in colour by Granada Television (two years before ITV's regular colour service began), The Flower Of Gloster was about four youngsters who crew a narrow-boat from North Wales to London and their adventures on Britain's inland waterways. In fact, the series was largely experimental in more ways than one, the tales being a mixture of plotted storylines, natural history and improvisation.
"The lead characters played themselves (all the character first names were the names of the actors) and any chance to take in a place of historical interest on their journey (Woburn Abbey, Stoke Bruerne Museum - which portrays the heritage of 200 years of inland waterways) was taken up by the series producer Bill Grundy. This all mixed in rather oddly with the fictional tales of haunted forests and 'bovver' boys.
"The plot involved Richard Doherty (Richard O'Callaghan), eldest son of Jim (Jim Doherty), a boatyard owner from Wales who is unable to deliver a new barge to London when he breaks his leg in an accident. So Richard takes the helm and is accompanied by his sister Elizabeth (Elizabeth Doherty) and they are soon joined by their young brother Mike (Mike Doherty) and their friend Annette (Annette Roberston), and for 13 weeks they traverse the waterways of west England passing towns, cities and villages.
"Chris McMaster, who the following year would bring a different type of children's action/adventure series to the screen when he devised Freewheelers, wrote the series. The name of the boat and series title was inspired by Ernest Temple Thurston's evocative account of a springtime journey by barge around the canals of Oxfordshire, Warwickshire and Gloucestershire, 'The Flower of Gloster' first published in 1911.
"Producer Bill Grundy went on to television notoriety when he interviewed the Sex Pistols on live television, inadvertently kicking off the whole punk rock era, and ending his own TV career."
"The film was shot on 16 mm with the sound on a separate tape.This required a special projector which we called a double header. When chairman or secretary of the Manchester Branch of IWA I approached the local Granada studio with a request that they show an episode at the branch meeting. They were surprised to learn that the projection room at the largest of the theatres in the Roscoe Building was equipped with the the right equipment. Arrangements were made to pay for the professional projectionist and on the night 400 members and friends enjoyed the episode shown in glorious high definition colour and sound. Presenting the episode with a full description of it making was Stuart Hall. This was certainly the largest ever Manchester Branch meeting.
"it is possible that the film still exists in some dusty Granada vault but it is doubted that in the present circumstances it will ever see the light of day, or be rebroadcast."
