The 77-year-old producer, songwriter and performer died following a gig in Spain, and some of music's biggest names have marked the sad news with statements and social media notes.

LaBelle, whose hit 1974 album Nightbirds was produced by Toussaint, says, "Allen was a gentle giant! Perceptive, kind and always open to your input and feelings. He knew how to listen and (was) never offended.

"He also introduced me to shrimp sandwiches, which I still love today! I just can't say enough good things about him!"

LaBelle plans to sing "a special song" he wrote for her, Don't Make Your Angel Cry, as a tribute to her late friend at her next concert.

Meanwhile, MCCartney recalled working with Toussaint in the late star's native New Orleans, adding, "I know what a sweet and gentle guy he was and a massive songwriting talent with songs like Fortune Teller, Southern Nights, Working in the Coal Mine and Play Something Sweet (Brickyard Blues).

"His songs will be cherished by people like me who will have fond memories of Allen forever. Deepest sympathies and love to his family from me and my family."

And Kravitz added, "I'm still in shock and heartbroken after hearing of the news of the passing of my longtime friend, brother in music, teacher, mentor and most gentle person you'll ever meet, Allen Toussaint. He was a true musical treasure and legend that New Orleans shared with the world. Thank you Allen for all the music, good times and the legacy you leave behind for everyone to continue to enjoy. Rest in Peace."

There were also tributes on Tuesday (10Nov15) from John Oates, Questlove and Toussaint's fellow New Orleans natives Harry Connick, Jr., Dr. John and Art Neville.
