Jethro Tull - A Song for Jeffrey, live at the Rolling Stones Rock and Roll Circus (1968)

Retrieved in deep web, also known as “Vimeo“, after YouTube took down this rare footage of Jethro Tull with Ian Anderson on flute and vocals, Clive Bunker on drums, Glenn Cornick on bass and harmonica and future Black Sabbath’s founder Tony Iommi on guitar. Hope YouTube don’t take it down again!
