Glad it intrigued you! Over here most people don't think of it as a poem -- it's much more well known as being a not-quite-a-hymn sung at suitably important occasions (and at WI meetings).I've not read everything yet, but TJ's intrigued me, with the reference to Blake's poem in the title.
Mouse - Thank You for your vote! I'm delighted you liked it!
Was grinning when I saw that I'd got a vote last night I posted thanks on another thread by mistake - am blaming the Merlot!
