The Archie Show c. 1969 : First #1 song from a cartoon

Written by musicians Jeff Barry and Andy Kim and originally recorded by The Archie Show’s fictional bubblegum pop band the Archies (with Ron Dante, Andy Kim, and Toni White on vocals), “Sugar Sugar” skyrocketed to No. 1 on the U.S. Billboard “Hot 100” chart, where it stayed for four weeks. According to Dante, a promoter in San Francisco “took off the label before giving it to the top radio station there. He said, ‘Just play it! It’s a mystery group.’ The guy played it, and the phones lit up.”

The catchy tune (and the originality of the animated music-video concept) inspired a wave of Saturday-morning cartoons to follow suit by incorporating bands and music, like that time Scooby Doo met the Monkees. And while it was the first song by an animated band to reach the charts, it certainly wasn’t the last.
