So has anyone noticed anything strange happening in London?

Early Wednesday morning edit:

Okay, to extend on 'strange'... something's up with my powers and it's to do with London. I've been running through the usual scans and trying to drum up some people, and nothing so far, but something is really messing about with my powers. And I got this call from London, kids' voices singing "London Bridge is falling down" - that qualifies as our kind of strange, right?

If we can't find anything on the feeds and whatnot, can we go check it out in person?
