Sam Fender and Olivia Dean's 'Rein Me In' Becomes U. K. 's Longest Running No.
1 Single of All Time The UK's Official Singles chart has been turned on its head by an unlikely duo, as Sam Fender and Olivia Dean's "Rein Me In" secures a spot in the record books.
The song's 19 week reign at number one eclipses the previous benchmark set by Frankie Laine's "I Believe" in 1953, marking a milestone in British music history.
