Sam Fender and Olivia Dean have rewritten the U.K. chart record books with their collaboration “Rein Me In.” The song has now spent 19 weeks at No. 1 on the U.K. singles chart, giving the pair the longest stay at the top in the chart’s history.

The milestone pushes past a mark that had stood since 1953, when “I Believe” set the previous standard. That means Fender and Dean have ended a record run that lasted for roughly seven decades, making their single one of the biggest chart stories in recent U.K. music history.

The achievement also underlines the staying power of “Rein Me In,” which has continued to hold its spot week after week. Rather than a brief surge, the song’s success has turned into a historic run, keeping both artists firmly in the spotlight.

For Fender and Dean, the 19th week at No. 1 is more than another chart update. It marks a rare moment when a current release overtakes one of the oldest benchmarks in British pop, setting a new target for future hits on the U.K. singles chart.
