Elton John will release his official memoirs in 2019 after signing a new worldwide publishing deal with Henry Holt and Macmillan.

The book, billed as John's "first and only official autobiography," is currently in progress, with John working alongside Guardian music critic Alexis Petridis. The publisher promises a "no-holds-barred account" of his life.

"I'm not prone to being a nostalgic person.

I'm often accused of only looking forward to my next gig or creative project.

It's come as quite a surprise how cathartic I am finding the process of writing my memoirs," John said in a press release announcing the project. "As I look back, I realize what a crazy life I have had the extreme privilege of living."

"I have grown up in a period of extraordinary change in our world - and have had the joyful honor of rubbing shoulders and working with so many of the people at the heart of these changes," he added.

"My life has been one helluva roller-coaster ride and it's still lumbering on. I hope readers will enjoy the ride too."
