Finally our readers are subjected to the usual interrogation. There are quite a few matters arising.
When Pete mentions that Jo writes Grimdark he is, of course, referring to our own Joanne Hall, not that Abercrombie fellow who doesn't have nearly the same body count.
David makes mention of something called BRP. That's Chaosium's Basic Role Playing system, which formed the core of all of the rule sets they produced back in the day.
If you'd like to know more about David's work with the Cthulhu mythos, he has a guest post about it on Pete's blog.
The deadly Call of Cthulhu scenario that David refers to is "Roots" by Simon Brake which appears in the collection, Things We Leave Behind from Stygian Fox.
And finally, Wikipedia has little to say about alternative versions of the magpie song, other than to confirm Pete's assertion that the version he is using is older than the one used by the TV programme.
