The Britain’s Got Talent star took to the stage at the historic Philharmonic in Liverpool on February 16, 2025, and left the audience utterly spellbound.

From the first few notes, Christmas’s voice evoked comparisons to a young Shirley Bassey — and not just because of the song choice. Her control, tone, and sheer vocal power lit up the hall.
Few singers can truly conquer the challenging high notes of “Diamonds Are Forever,” but Christmas didn’t just hit them — she soared.
There was a timelessness to her presence that night. Draped in elegance, she commanded the stage with confidence and poise, building toward a dramatic crescendo that brought the audience to their feet. It was a masterclass in live performance.
Though her name first became known to millions on Britain’s Got Talent, it’s moments like this that prove Sydnie Christmas is not just a talent-show standout — she’s a world-class vocalist in her own right.
Here’s what to know about “Diamonds Are Forever”
Originally written by John Barry and Don Black for the 1971 James Bond film of the same name, the song became one of Shirley Bassey’s signature hits — known for its sultry glamour and vocal demands.
Over the years, it’s been covered by artists across genres, but very few have managed to channel both the technical difficulty and the dramatic flair quite like Christmas did in Liverpool.
