Hi,Larry,
thank you for taking the time to stop by, always appreciated. On 'grey', yes that is the colour being referenced - it's how we spell it, 'Gray' is the family 2 doors up on the left.

I am in good company, I think, when you remember Tolkien's 'Grey Pilgrim' and 'Grey Havens' or was that edited over there?
Seriously speaking, I don't think it's too much to ask American readers/friends to make this small concession, that we Brits can use the spellings we are used to - after all we excuse the variations you use. Not just in spelling but stressing differs, sometimes markedly; you say O-ffence, we say o-FFENCE same with DE-fence (US) and de-FENCE (UK). It's usually quite easy to see what stressing the poet intends and providing it agrees with the needs of the line I have no problems with that. A little toleration never hurts, after all wasn't it Ben Franklin who said 'a man who can think of only one way to spell a word is lacking in imagination' or words to that effect. Come to think of it, that quote is probably what led to the situation now where we have 'two countries separated by a common language'.
