Hi Simmy,
Sorry it's taken me so long to follow up on your question. I'm afraid I still am not too clear on where Kidder's cottage was - in fact even David Morrissey and Spencer Leigh seem a bit hazy on it. It seems most likely it was near Leeds though (I found the Dance Hall around there), particularly as one of the newspaper articles of the time refer to it as being near Leeds. It's definately the 'holy grail' of One Summer fans now *lol*
I have heard a suggestion on who the 'other' Kidder was, but it's probably something best left in the past (Particularly as I'm not certain it was true!)
