New Billy Joel documentary, 'And So It Goes,' airing on HBO this summer 

Billy Joel is about to get the documentary treatment — and a reasonably exhaustive treatment at that. HBO announced Tuesday that Susan Lacy, the longtime producer of PBS' "American Masters," had been granted "unprecedented access to never-before-seen performances, home movies, and personal photographs, along with extensive, in-depth one-on-one interviews." The premium network said those will form the basis of the two-part film, "Billy Joel: And So It Goes," which will air sometime this summer and also stream on Max.

In a statement, Lacy said, "For those who think they know Joel’s story, as well as those who are not as familiar, I believe this two-part film is both a revelation and a surprise. I was drawn to his story as someone who knew little at the outset, and was astounded at how autobiographical his songs are and how complex his story is. We are gratified that Bill trusted us with his story, which we have told as honestly as possible, diving into territory which has not been explored before."

Lacy was the creator and showrunner of PBS' "Masters" over a 27-year run there before leaving in 2013 for HBO as part of what she called at the time "a very nice multiyear deal" to produce biographical films.

For the Joel project, HBO said she'll be joined by Jessica Levin — also billed as a director and producer.

In a news release, HBO said "Billy Joel: And So it Goes" will explore "the love, loss, and personal struggles that fuel his songwriting."

Joel, 75, announced on his website March 11 that he was postponing his current tour for four months following surgery and physical therapy for an unspecified medical condition, and that he expects to make a full recovery. He is still scheduled to play Yankee Stadium, Citi Field and MetLife Stadium this summer.
