Thanks everyone, this is one of the hardest parts of the whole thing, and I appreciate all your suggestions. Seems like everyone has their own favourites and so I'm not sure I'll ever find something that everyone will agree on.
One thing I've been trying to do is find something with lots of different sounds in it. So "unclear moon" .. not a great title, but its got different sounds in it and is more fun to say than "manic moon", for instance. Titles are tough..
Not if there's only one lost moon though ... the one you have to find. Still .. either could work!
I'm warming to that name, and I think about it every now and then.
