Aaaargh reading this has made me wish I'd read this edition, it sounds excellent.
I used to buy the magazine from WH Smith several years ago, I have some of them along with 2 or 3 of the separate little It Happened to Me compendiums.
But alas the shop didn't always stock it - seemed somewhat hit and miss, there was never any regularity to it, we would just look each time we were at the shop and it would either be there or it wouldn't - and we could never find it anywhere else. Therefore as a consequence I haven't been able to buy it for quite some time.
