Sam Fender surprised fans at Olivia Dean‘s O2 Arena concert with a performance of ‘Rein Me In’ – check out footage of the moment below.
The song originally featured on Fender’s third and latest studio album ‘People Watching’, but later took on new life during his huge London Stadium gig last year, when he brought Dean out in front of the 80,000-strong crowd and performed a collaborative rendition.
The two of them would then join forces twice more at shows to share the duet – both held at Fender’s huge homecoming shows at Newcastle’s St. James’ Park, and last June, they officially released the track.
Since then, it’s become a fan-favourite, winning the BRIT Award for Song Of The Year, and scoring Fender his first ever Number One single. The track broke the record for the most consecutive weeks spent in the Top 40 before reaching the top, and has now spent nine non-consecutive weeks at number one on the UK Singles Chart.
To celebrate, Fender and his saxophonist, Johnny “Blue Hat” Davis, surprised fans at Dean’s headline show at The O2 on Friday (May 1) to perform together for the first time this year.
Check out footage of the moment below.

It comes during Dean’s ongoing UK and Europe headline tour, which opened in Glasgow last month. NME caught the first show and gave it a four-star review, which read: “As the energy soars to the end of the show, Dean forgoes the tired theatrics of an encore and goes straight into the electric ‘Man I Need’.
“Thousands of fans raise their hands and belt the earworm hooks back to the ever-captivating Olivia Dean. It’s a moment of pure, confetti-coated euphoria: a grand finale befitting our newest pop superstar.”

In other news, she recently revealed that her hit song ‘Man I Need’ was nearly not released as a single, and shared that she is open to taking part in Strictly Come Dancing.
As for Fender, he recently raised £50,000 from ticket sales on his ‘People Watching’ tour for the charity Youth Music.
He also won Alternative/Rock Act at this year’s BRITs – meaning he has five trophies to his name, as well as the 2025 Mercury Prize for ‘People Watching’.
