At Musical Con 2024, the annual celebration of musical theatre on London’s legendary West End, one performance stole the hearts of everyone in the room: Sydnie Christmas’s powerful and emotional rendition of “She Used To Be Mine” from Waitress. A fan-favorite song known for its raw honesty and emotional complexity, the number requires both vocal power and deep sensitivity — and Sydnie delivered both in abundance.

The atmosphere inside the venue was electric as theatre lovers gathered for a weekend filled with panels, workshops, meet-and-greets, and, of course, show-stopping performances. When it was announced that Sydnie Christmas would take the stage to sing one of the most iconic ballads in modern musical theatre, the anticipation soared. From her first note, it was clear that the audience was about to witness something unforgettable.

Dressed in a classic, understated outfit that let her voice shine, Sydnie stood beneath soft stage lighting that created an intimate, almost cinematic mood. The piano introduction began, and the room fell completely silent. From the very first verse, Sydnie brought a breathtaking vulnerability to the performance. Her tone was rich and warm, and she built the song slowly, carefully, allowing the emotional tension to grow with each lyric.

“She Used To Be Mine”, written by Sara Bareilles, is sung by the character Jenna in Waitress and reflects on a woman who no longer recognizes herself. It’s a song of loss, resilience, identity, and inner strength — themes that Sydnie channeled beautifully. She didn’t just sing the words; she lived them. Her delivery was filled with nuance — moments of fragility and moments of defiance — creating a dynamic, deeply human portrayal.

As she reached the chorus, Sydnie’s voice soared effortlessly through the demanding vocal lines, commanding both technical precision and heartfelt emotion. Her vocal control was astonishing, especially during the climactic lines where the melody stretches into powerful high notes. Yet it was the moments of quiet — the gentle phrases, the slight tremble in her voice — that truly moved the audience.

By the final note, many in the crowd were visibly emotional. The applause was immediate, loud, and long-lasting. Some fans stood up, others wiped away tears, but all knew they had witnessed a special moment — one that elevated the entire convention.

After the performance, Sydnie spoke briefly about her connection to the song. “This is one of those songs that just grabs your heart. I’ve loved it for years, and singing it here — in the heart of the West End, surrounded by people who love theatre as much as I do — it’s overwhelming in the best way.”

Her rendition quickly went viral on social media, with fans sharing clips and praising both her vocals and the emotional honesty she brought to the stage. It was a standout performance in a weekend full of talent, and for many attendees, it was the absolute highlight of Musical Con 2024.

Sydnie Christmas didn’t just sing a song — she told a story, and she made everyone feel it. In doing so, she proved once again why she’s one of the most exciting rising stars in musical theatre today.
