Not quite a paperback writer: Paul McCartney to publish children's book

Paul McCartney’s grandkids have apparently inherited some of their grandpa’s creativity.

One of them greeted him with “Hey, grandude” — which the former Beatle first adopted as his new nickname, then used as a title for the children’s book he plans to write.

Hey, Grandude stars a magical man (known as Grandude, of course) and his four grandchildren as they go on adventures together.

The picture book is scheduled to be published in September 19.

You can read more about Hey Grandude and watch a video of McCartney announcing it on The Guardian’s website.
