Tonight at 7 PM, 8 Tracks and 45s kicks off with one of the most unmistakable openings in American pop‑rock history: Three Dog Night’s jubilant, full‑throated anthem “Joy to the World.” Few bands captured the spirit of the early ’70s quite like Three Dog Night — a group whose harmonies, energy, and genre‑blending sound helped define an era. Their music was everywhere: on the radio, in jukeboxes, and echoing across summer festivals. And with “Joy to the World,” they delivered a song that still feels like pure sunshine more than 50 years later.
