Memories of Thorpe and Hancock

I recently came across this display of dancing program and I am sure that there are a lot of people who went for dancing lessons at the Thorpe and Hancock school of dancing. Their formation team represented the East Midlands in the televised, in what was in those days was called Come Dancing. I recognize a few of the names in the production. The part 1/6 titled Twins In Harmony  G and J Barker are Gill and Jean Barker our good neighbours when we moved into Bancroft Lane in the forties, and J Brown could be Janet Brown another family neighbour. There is a R North in several scenes and I wonder if this could be Rosemary North and if so I believe she went on to be a professional dancer. Can anyone remember the dances at the parochial hall in sixties they are good memories.
