I don't to hand and it's really late here. I can try and look tomorrow if work isn't too busy. I have a feeling it's in an interview with people from the various groups that was in a non-English documentary, maybe Dutch. But I think I've read it too. I'll do my best so long as you don't mind waiting a while.
No worries! I'd really like to see it, so feel free to tag me in a post or send a DM whenever it is that you come across it again. I'm sure others here would be interested as well!
