Last night, the Duchess attended the opening night of the popular musical '42nd Street', the song and dance, American dream fable of Broadway, at the Theatre Royal, Drury Lane.

The production is being directed by the show’s co-author Mark Bramble, who has directed many award-winning previous productions of 42nd Street on Broadway and around the world.

Sheena Easton—the Grammy Award winning artist who has sold over 20 million records around the world—is making her West End debut in the production.

The plot is described, "Young Peggy Sawyer is fresh off the bus from small-town America and just another face in the chorus line on Broadway’s newest show. But when the leading lady gets injured, Peggy might just have the shot at stardom she's always dreamed of..."

Kate was seated in the Royal Box alongside Lord Michael Grade, left, and Dr Johnny Hon, right. She was accompanied by William's private secretary, Miguel Head, and Rebecca Deacon's assistant, Sophie Agnew, again tonight (you can see them standing behind her in the Royal Box) as I guess Becca will still be on her honeymoon.

Afterwards, the Duchess joined the cast and crew on stage and she was presented with her very own pair of tap shoes by co-producer Lord Michael Grade.

Ahead of the show, Kate met with 12-year-old Ollie Duell who gave her the show's program. He suffers from a complex bowel and stomach condition and has benefited from the services of East Anglia's Children's Hospice (EACH). Kate attended the production in aid of EACH, a charity which she has been patron of since early 2012. EACH supports families and cares for children and young people with life threatening conditions.

It has outgrown its hospice at Quidenham and is currently fund-raising for a new purpose-built one called 'the nook'. Kate helped launch the nook appeal back in 2014 and revisited the hospice earlier this year for an update on the appeal. They have achieved half of their £10 million goal so far. This evening, the audience is helping to fundraise towards the appeal to help make EACH's vision a reality.
