Good dancing - never mind great dancing - calls for an investment of imagination in every point of the foot, every raise of the arm. Why otherwise do the constant drill of turning out the leg, stretching the instep, taking fifth position, if the performer does not find something to stimulate them to make it personal, to dream it, to claim it for their own nuance? Does the violinist play Schubert thinking that it is enough just to get the notes right?

What should a choreographer set before a Prince for a Royal Gala performance when his finest hour is a portrayal of Royal buggery with a hot poker? Well, possibly (sotto voce) clogdancing cobblers and pegleg pirates might be found more suitable, and plenty of children on stage. So peglegs and clogdancing is what Prince Charles will duly be served tonight at the celebration of 20 years of Birmingham Royal Ballet. These are not times to be challenging any more.

Prince Charles and the Duchess of Cornwall will attend Birmingham Royal Ballet’s 20th anniversary gala tomorrow night celebrating two decades in Birmingham for the company which was once Sadler’s Wells Theatre Ballet. The Prince of Wales is President of BRB and the Duchess is Patron of Elmhurst School of Dance, now Birmingham-based and associated with BRB. The move out of the capital made in 1990 by then director Peter Wright was seen as high-risk, but it was backed by Dame Ninette de Valois, then 92, who also approved of Wright’s succession by the young choreographer David Bintley.

Peter Wright’s superlative production of The Nutcracker has returned to Birmingham Royal Ballet's repertory for Christmas, a production he created for the company in 1990 and to my mind superior to any other presented in the UK today. Magic, the awesomeness of the Tchaikovsky score, are realised upon the stage and shown in its dances with a childlike sense of fantasy. The Christmas tree rises, the rats play, the snow-goose flies - and the audience gasps.

Lush, romantic storyballets are as scarce as hens' teeth these days, despite the longing of much of the ballet audience to see them. Not because they're too elementary for today's dancemakers, I'd guess, but because to make one with lively dancing characters (male, female, young, old, good, bad, rich, poor), with a flowing story, lashings of set opportunities and an atmospheric score, takes multiple theatre skills few choreographers now develop. David Bintley's Cyrano is one of these rare birds, a truly skilled family ballet with all of the above.
