“The Definitive Collection” (John Lee Hooker)
John Lee Hooker, circa 1965, based on the earnest expressions of the studio audience dancers, resplendent in their neckties or turtlenecks. JLH looks to be laughing, internally, at least. Live on some BBC show.
Bonus: Fela Kuti and the Africa 70 playing live in Europe with Jethro Tull (now, that's a combo I'd never expect)
