The American pop-rock duo Zager and Evans end a six-week run at the top of the charts with their ponderously titled single “In The Year 2525.” With lyrics focused on the ominous effects of future technology, it would be their one and only hit. Zager and Evans never returned to the pop charts after their triumphant debut in the summer of ’69. The disbanded just two years later, in 1971. In their very brief career, however, they spent longer atop the pop charts (six weeks) than many more enduring acts. Like so many stars whose hits have not stood the test of time, however, they have been nearly expunged from cultural memory.
