I agree with Jack on Kleinzeit, except to say that perfectly healthy hypochondriacs will get a lot out of it too. There's a gag that he uses two or three times where a doctor asks K. about some perfectly innocuous symptom (When you pee, does it sometimes come out in two streams?), and then says something vaguely ominous when he says "Yes, but isn't that normal?". ("Normal, yes - that's the spirit!")

I can't think of any bands named out of Riddley Walker, though. I'm not sure, but I suspect its the speling puts peepl off - I could imagine any number of bands / albums / etc called "Little Shining Man", "Widow's Bell" or whatever, but using the actual spellings would make too strong a link back to the book.
