It was all about Jo-El Sonnier at the Museum of the Gulf Coast Thursday.

The popular Cajun musician and Grammy award winner was in town with his two children’s books and cookbook, Ayeee Cajun Power Sauce and more as fans lined up to get autographs before a quick concert.

Esther Benoit, former owner of Esthers Seafood under the Rainbow Bridge, brought along granddaughter Courtney Hollier and Benoit’s first great-grandbaby Peyton.

She picked up a handful of Sonnier’s books for gifts before standing in life to have him autograph them.

Kathleen Williams grabbed a bottle of hot sauce and one of Sonnier’s music CD’s.

“My daughter-in-law might get it,” longtime fan Williams said of the book. “And she might not.”

Sonnier’s life is the subject of two books, “The Little Boy Under the Wagon,” which talks about his challenging childhood. Born to French-speaking cotton sharecroppers, his parents kept him under a wagon for protection while they worked the fields. He struggled socially at school because, when he started, he spoke only French. His sister-in-law, Dr. Shirley Strange-Allen, recognized some of his behaviors as consistent with Asperger’s syndrome, a form of autism.

The cookbook, “There’s Somethin’ in the Swamp…. and It’s for Dinner!,” features some of Sonnier’s favorite recipes.

Sonnier was accompanied by museum inductee and fiddler David Varnado.
