On December 31, 1974, Dick Clark’s New Year’s Rockin’ Eve brought the ultimate lineup to ABC’s late-night block: Chicago, The Beach Boys, The Doobie Brothers, Herbie Hancock, and Olivia Newton-John. Chicago’s “Wishing You Were Here” was still climbing the charts, and the Beach Boys joined them for an unforgettable live moment. The night also gave us The Beach Boys’ iconic “Good Vibrations” and “Darlin'”—with Chicago’s horn section adding even more magic. What a way to ring in the new year!
