The brewing Jimmy Buffett musical doesn’t have a title yet, but it’s got a plot, plus dates for a world premiere production at San Diego’s La Jolla Playhouse in the late spring of 2017 — which would put the production on track to land on Broadway as part of the 2017-18 season, if a subsequent transfer to New York were to materialize.

No formal Broadway intentions have been announced for the Buffett project, but New York seems near-certain to be in its producers’ sights, given a producing team that includes film producer Frank Marshall and Broadway regulars Mindy Rich, Anita Waxman and Beth Williams. Director Christopher Ashley’s Broadway credits include Tony winner “Memphis” and “Xanadu.”

With news of the La Jolla run also comes an outline of a plot, which will focus on a singer/bartender named Tully who falls for a career-focused tourist. Buffett, an author as well as a singer-songwriter, has made use of the name Tully in the past with Tully Mars, the protagonist of his 2004 novel “A Salty Piece of Land” and, previously, of a short story published in 1989 collection “Tales from Margaritaville.”

The musical will include both pre-existing songs and original tunes from Buffett, with a book written by Greg Garcia (“My Name is Earl”) and Mike O’Malley (also an actor whose TV work includes “Glee”).

The still-untitled show will begin previews May 16, 2017 ahead of a May 28, 2017 opening at La Jolla, where Ashley is artistic director.
