BBC Television crews descended on Uxbridge College to film a follow-up on progress for its documentary The Choir.
Student Chelsea Campbell (17), who is taking a First Diploma in Performing Arts, was the star of filming at the Hayes Community Campus.
Chelsea, who lives in Northolt, is a former pupil of Northolt High School, in Ealing borough, where youngsters were auditioned for The Phoenix Choir, which became the subject of the three-part documentary The Choir.
The show, which told the story of pupils being coached to world competition standard in nine months, was shown on BBC2 at the end of last year.
The crew came along to the College on 26 June to catch up with Chelsea's progress since the show.
They filmed Chelsea and her classmates in rehearsals for end of year Variety Show, and at the final performance in the evening.
Chelsea, who is doing a First Diploma in Performing Arts, said: "Being in The Choir really did encourage me with my singing - I have never had singing lessons or anything, although I have always enjoyed it and sang along to the radio. I was more into dancing, which I have been doing since I was two-and-a-half years old.
"Being here means I can be myself - I am doing what suits me and I love it."
Chelsea has been taking dance classes at Cheryl Honour dance school in Southall since she was a young child.
Simon Clark, section manager for performing arts at Uxbridge College, said: "Chelsea has made great progress and gone in leaps and bounds in the adult learning environment of Uxbridge College. Even though she's a star already thanks to The Choir, she is a great singer and dancer and could make a real success of whatever she chooses."
The show is due to be broadcast on BBC2 on a date to be confirmed.
