So last night, as promised, we used Morris to explain why the sky is blue.
I got to hug Sian Lloyd who - only for the purposes of the show, Mr Opik - is an old and very close friend of mine.
Ezra and Noah were centre of the set, and we danced Banks of the Dee - or parts of it - more times than we ever have in our lives (and we've danced Banks of the Dee pretty often, I can tell you). This was pretty tough for us, but Peter K, John M and William had to play that tune - and sometimes just the A tune - over and over for an hour and half.
The crew filmed us from overhead, dancing with different colour hankies, to illustrate the way blue light is scattered out of sunlight. I'm imagining it will have a sort of Busby Berkeley effect.
Of course, even with all that practice, the hays still weren't as slick as they should be - or even in some cases, actually correct. When it all gets edited down to one minute, I'm sure they'll edit out the collisions. Either that or they'll edit the rest out, and use Morris dancers colliding as a metaphor for sunlight hitting the moleculse in the air.
