I wanted to clear out those last two videos to make room for Dr. John, who passed away on June 6th at age 77. From wiki:
As a young man Rebennack was interested in New Orleans voodoo, and in Los Angeles he developed the idea of the Dr. John persona for his old friend Ronnie Barron, based on the life of Dr. John, a Senegalese prince, a medicinal and spiritual healer who came to New Orleans from Haiti. This free man of color lived on Bayou Road and claimed to have 15 wives and over 50 children. He kept an assortment of snakes and lizards, along with embalmed scorpions and animal and human skulls, and sold gris-gris, voodoo amulets that protected the wearer from harm.
Rebennack decided to produce a record and a stage show based on this concept, with Dr. John serving as an emblem of New Orleans heritage. Although initially the plan was for Barron to front the act assuming the identity of “Dr. John”, while Rebbenack worked behind the scenes as Dr. John’s writer/musician/arranger/producer, this didn’t come to pass. Barron dropped out of the project, and Rebennack took over the role (and identity) of Dr. John. Gris-Gris became the name of Dr. John’s debut album, released in January 1968, representing his own form of “voodoo medicine”.
