What Year Is It (36)?

A tumultuous year in the U.S., but great for Top 30 pop hits, like Marvin Gaye’s “I Heard It Through the Grapevine”; The Fab Four’s “Hey Jude”; “Tighten Up” from Archie Bell & The Drells; The Queen of Soul’s “Chain of Fools”; and Otis Redding’s “Sittin’ on the Dock of the Bay.”
