Helena, hope you get to see this at Sadler's Wells (and there is a video too).
To give you more of a flavour, this is a hugely intelligent and amusing ballet, a rare combination. It's about endangered species, man's cruelty, the fragility of the planet - but all done with a lightness of touch, nothing politicised or forced but it does make you think. It's set in a cafe, penguins as waiters, glossy stilletoed socialities clad in zebra prints.
The humour comes in the foot-tapping tuneful score and some jaunty choreography - I can remember Sandra Magwick as a flea (or maybe an other insect) running amok with some morris dancers. More serious is a pas de trois for a child with two parent figures, circling the stage in hope. It ends with a really clever image of Noah's ark.
The designs are great, very colourful - various backdrops, good lighting, great slabs of colour. Tha animal (and human) costumes are clever too.
It's a must see because it's a clever piece of theatre: the idea (both serious and humourous), the design, music and movement all combine really well. Which said it is memorable as a whole - but (my usual caveat with Bintley, sorry) none of the choreography is memorable in itself.
But go - I'm sure you will enjoy it.
