Malcolm John “Mac” Rebennack (November 21, 1940 – June 6, 2019), better known by the stage name Dr. John (also Dr. John Creaux, or Dr. John the Night Tripper), was an American singer, songwriter, pianist and guitarist, whose music combines blues, pop, jazz as well as zydeco, boogie woogie and rock and roll.

Active as a session musician since the late 1950s, he gained a cult following in the late 1960s following the release of his album Gris-Gris and his appearance at the Bath Festival of Blues and Progressive Music.

He performed a wildly theatrical stage show inspired by medicine shows, Mardi Gras costumes and voodoo ceremonies. Rebennack has recorded over 20 albums and in 1973 scored a top-20 hit with the jaunty funk-flavored “Right Place Wrong Time”, is still his best-known song.

The winner of six Grammy Awards, Rebennack was inducted into the Rock and Roll Hall of Fame by singer John Legend on March 14, 2011. In May 2013, Rebennack was the recipient of an honorary doctorate of fine arts from Tulane University. He was jokingly referred to by Tulane’s president, Scott Cowen, as “Dr. Dr. John”.
