The Rolling Stones Rock and Roll Circus was a concert show organised by the Rolling Stones on 11 December 1968. The show was filmed on a makeshift circus stage with Jethro Tull, the Who, Taj Mahal, Marianne Faithfull, and the Rolling Stones. John Lennon and his fiancee Yoko Ono also performed as part of a one-shot supergroup called the Dirty Mac, featuring Eric Clapton, Mitch Mitchell, and Keith Richards.
Henry Saint Clair Fredericks (born May 17, 1942), who uses the stage name Taj Mahal, is an American blues musician, a singer-songwriter and film composer who plays the guitar, piano, banjo, harmonica, and many other instruments. He often incorporates elements of world music into his works and has done much to reshape the definition and scope of blues music over the course of his more than 50-year career by fusing it with nontraditional forms, including sounds from the Caribbean, Africa, and the South Pacific.
