One of the songs written by Tom Minchin for Matilda: The Musical is being turned into a picture book.

The book will be based in the song When I Grow Up and be illustrated by Steve Antony.

Publisher Scholastic UK says the book will imagine, “with equal amounts of humour and pathos”, what adult life is like from a child’s perspective.

Minchin said: “I adore Steve’s work. It’s been a thrill to watch him develop his gorgeous illustrations—I can’t wait to hold a copy.”

When I Grow Up will be published in the UK in October and the US in summer 2018.
