This is one Postman Pat Special I seemingly, watched the most on YouTube. Quite surprised it was released on Christmas Day in 1991. Wish I had VHS release of this (New Video/Bumper Collection) with/without VHS "The Very Best of Postman Pat".
This special episode does give numerous trivia points, firstly Carole Boyd first gives voice performance (of Sara and Julian Clifton, Julia and Katy Pottage, Mrs. Goggins, Miss Hubbard and Dorothy Thompson) - while Ken Barrie still voices the others, even Granny Dryden. First appearance of Ted's lorry, Pat's son Julian Clifton and PC Arthur Selby. Quite a laugh at times when the reverend goes "Good heavens!" on his bike downhill crashes into the barn Thompson Ground.
Some goofs which I couldn't forget, like when they arrived in Ingledale, someone (Peter Fogg) looks to be driving Ted Glen's lorry, and then passing the other way instantly on his motorbike, and Miss Hubbard didn't pay for the eggs she bought from George Lancaster.
Overall, quite a popular Postman Pat special.
