That's the first 50 issues of Kerrang! up and I will try and do the other 50 upto issue 100 tomorrow, however I did find a bug (I think) when I tried to add 1982 to issue 27 the only went back as far as 1985!!
From the date of this issue you will find that they published two in the same month and then from I think issue 50 it’s officially two publications a month! Plus when they got to around the 90th issue they had Karrang extra etc etc, After that I kept going until issue 100 and stop buying it altogether, because the style of the magazine started to change and I didn’t like it from there onwards!!
