Book of spooky tales/articles for children

[meatina]

Hello,

I've been trying to find a book I read as a child, that had some snippets of poetry, some stories by different authors, and at least one non-fiction piece. I've tried googling some of the names of the stories, but no joy.

Here's what I know/can remember:

-It would have been published in the UK no later than about 1993 - however it's probably from the 80's.
-It was a paperback with a blue cover, possibly with a church window and a bat on.
-It featured a Shakespeare sonnet in it - "Now is the time of night"
-There was a story/poem by (I think) Joan Aitken called "The Nine O'clock Horses" about horses that spirit away children that stay out late at night.
-There was a story about a boy who did a brass rubbing of a skeletal knight
-One story was about a ghostly goalkeeper 
-Possibly the same story had a boy explaining to his little sister about ghosts, she wasn't scared but he was told of by his mum for scaring her - all the sister had said was "poor man that you can see through". He'd explained that you could see through ghosts, a bit like you could see the bones of her fish. 
-There was both a story and a non-fiction piece on Herne the Hunter
-The last story was about a very young stonemason who dies carving an angel on a church
