Most issues listed here as 1985 since that is the (P) & (C) date on the labels, but there is hard evidence that the UK release date was early January 1986. Most like all other issues were released then too. January releases are always (P) & (C) the year before as they have to be registered before they can be released. The January release date is given in the 4th Jan 1986 issue of the UK music industry trade publication Music Week - https://worldradiohistory.com/UK/Music-Week/1986/Music-Week-1986-01-04.pdf
