It’s almost weird that Paul McCartney doesn’t already have a children’s book out.

Sir Paul has conquered almost every challenge in his amazing seventy-six years, but he has waited until now for his first foray into children’s literature. The singer just topped the Billboard chart with his new album Egypt Station, but soon might top your bookshelf too with his book Hey Grandude!

The just announced picture book is scheduled to arrive in September of 2019, and is inspired by his experiences as a grandfather. “It’s called Hey Grandude!” McCartney explains in a new video. “Why? Well I’ve got eight grandchildren and they’re all beautiful, and one day one of them said to me “Hey Grandude!” I said “What?” and I thought, I kind of like that, so from then on I was kind of known as Grandude.”

Of all the McCartney nicknames, Grandude has quickly shot to the top of the list. The book features a magical grandfather and his four grandchildren who go with him on adventures. “I wanted to write it for grandparents everywhere, and the kids” he says. “It gives you something to read to the grandkids at bed time.”
