Ellie, thanks. I've always known Highheidyin (though only in speech, never seen it written down) and a Heid Highheadyin sounded quite logical! It doesn't work with the letters given, though...
SpareEd has given the ok for the post, so here's a PDF (less the entry coupon, I thought that best) - if you want to print it, open the link, close the "Sign in" box that might appear & you should see a black bar at the bottom of the screen - click the printer symbol on the far right of that bar.
You might need to adjust your printer settings - eg, mine says "Fit to printable area".
