It never occurred to me (until tonight) to dig deep in the oeuvre of Zager and Evans, who are known almost entirely for their No. 1 hit song in 1969, In the Year 2525. Zager and Evans are famous for being one of the only bands to have a No. 1 and never having another charting single.
But Zager and Evans did not just disappear. And they were not forgotten. This song was apparently used in a movie that had Jack Black in it. And a YouTube commenter said this:
So Zager and Evans are immortal for smart dancing.
