Watch Sam Fender & Olivia Dean play ‘Rein Me In’ at Lollapalooza 2026

When music history collides with a massive festival stage, the results are often pure magic. That’s exactly what happened at Lollapalooza when Olivia Dean brought the heat and Sam Fender onto the T-Mobile stage for a special performance of their hit track, “Rein Me In.”

The energy was palpable as the duo delivered the song, marking a moment that went far beyond a simple concert. This performance wasn’t just about entertainment; it was a celebration of an achievement that redefined what a single can mean in music. The song itself has carved out an extraordinary place in history, now holding the title for the longest-running UK Number One single of all time.

As they took the stage, Dean reflected on the emotional weight of their shared success. She spoke about her recent album, The Art of Loving, sharing that it had been a profoundly healing experience and a journey of self-discovery. It was through this music that she explored what life truly means to her, adding deep personal resonance to the public celebration.

Adding another layer of excitement to the story, Dean shared her pride in performing “Rein Me In” live in America with Fender. This performance became a monumental moment, celebrating the song’s status as a Guinness World Record holder and a benchmark for UK musical success.

The track’s journey to the top spot was meteoric. It took 35 weeks to reach Number One on the UK charts after its debut, demonstrating an incredible staying power that cemented its place in music history. This achievement followed Fender’s own remarkable run, which broke the record for the longest-running number one single.

The collaborative success wasn’t just limited to the stage; it extended into industry recognition. The pair celebrated their combined accomplishments with multiple accolades, including Song Of The Year at the BRITs 2026 and the Songwriter Of The Year award at the Ivor Novellos for Fender. Dean also received the Best New Artist statue at the BET Awards, further cementing their status as forces shaping contemporary music.

Their joint success is a powerful reminder that music doesn’t just entertain—it creates records, inspires reflection, and holds onto history. The story of “Rein Me In” serves as a vibrant example of how a shared artistic vision can achieve something truly extraordinary on a global scale.
