BAND BIO
Founded by Haynes, Woody, and drummer Matt Abts in 1994 as a power-trio, Gov't Mule has, over the course of eight studio albums, several more live projects, and over 1300 concert performances, built both an extensive, evolving body of work and a devoted fan base. In addition, the band has sold 1.5 million downloads on its website mule.net, sold over one million albums, and received a Grammy nomination. Keyboardist Danny Louis joined as a full-time member in 2003. With Hess leaving to pursue other opportunities, Haynes sees the addition of Jorgen as connecting the past and future of Gov't Mule: "Having worked with Jorgen over the last several months, we are very excited to explore some new directions while at the same time going back a little closer to our roots."

(from last.fm) Malcolm John "Mac" Rebennack, Jr. (born November 21, 1940), better known by the stage name Dr. John (also Dr. John Creaux), is an American singer-songwriter, pianist and guitarist whose music combines blues, boogie woogie and rock and roll.

Dr. John has been making his own idiosyncratic music since the 1960s. Along with Professor Longhair, Dr. John is heir to the rich New Orleans tradition. He is perhaps best known for "Right Place, Wrong Time", an international hit in 1973, reissued and used on soundtracks many times since.

Born in New Orleans, Louisiana, his professional musical career began as a session musician in New Orleans in the 1950s. Early on he also played guitar and was often known as Mac Rebennack. He switched to the bass ("the lowest time of my life"), and then the piano after his index finger was nearly shot off protecting his bandmate and longtime friend Ronnie Barron. He gained fame beginning in the late 1960s and early 1970s, with music that combined new orleans-style rhythm and blues with psychedelic rock and stage shows that bordered on voodoo religious ceremonies, including elaborate costumes and headdress. For a time he was billed as Doctor John, The Night Tripper. The name "Dr. John" came from a legendary Louisiana voodoo practitioner from the start of the 19th century.

Dr. John has also done vocals for Popeyes Chicken & Biscuits' "Luv dat chicken…" jingle, as well as the theme song ("My Opinionation") for the early-1990s television sitcom Blossom. His movie credits include Martin Scorsese's documentary The Last Waltz (in which he joins The Band for a performance of his song "Such a Night") and Blues Brothers 2000 (in which he joins the fictional band The Louisiana Gator Boys to perform the song "New Orleans").

In January 2008 Mac Rebennack, Dr. John, was inducted into The Louisiana Music Hall Of Fame.
