Hi Paul_Roberts, I'm sorry to hear your relative was involved (and that it's been 6 months since your post!) I don't know if you'll check this.
I went to the 70th commemorative event, it was a really busy night, the pub was packed and it was quite respectful to the events of 1941. Not sure it'd be of any use, but I'd be happy to chat to you about it if you'd like to PM me.
I am trying to track down the historian who organised it, Eddie Steele (Steel?)
I briefly spoke to him that night and he had some great info about my Suttons research, so I asked for his phone number or email address, but he told me to just pop round to his house any time...
I don't suppose he is a member of this site? I don't feel right just turning up at his house (he didn't give me the address, just roughly described it).
