Britain's Got Talent fans were left outraged after a 92-year-old Oscar-winning film star was axed from the show.
Although the performance did not appear on the main show, the star still featured in spin-off Britain's Got Talent: Unseen.
Shani Wallis, 92, played the role of Nancy in beloved 1968 film musical Oliver!, which won six Academy Awards.
Addressing the BGT judges, Shani said: 'I was here on this stage 70 years ago but you will probably remember me as the female star of the Academy Award winning motion picture Oliver!'
Alesha Dixon exclaimed in response: 'Nancy!'
Meanwhile, Amanda Holden stood up and said: 'Oh you were Nancy! I know who you are. Of course she's Shani Wallis.'
To which Alesha chimed in: 'Wow, what an honour.'
Shani then proceeded to perform a rendition of As Long As He Needs Me, having memorably sung it in Oliver!
She received a standing ovation from the audience, with Alesha saying: 'This is so beautiful because you are 92 years old doing something that you love so you're my hero.'
'You are an inspiration to all of us.'
Amanda added: 'I am starstruck.'
'I can't believe your age!' Simon remarked while KSI admitted he had never watched the film.
He added: 'But I have to see it after this because you sang that beautifully.'
All four judges voted to send Shani through to the next round of the competition.
However, some viewers shared their disappointment that she had not been featured on the main Britain's Got Talent programme.
One wrote: 'For some unbeknownst reason it wasn't shown on TV, 92 year old Shani Wallis (Nancy in the Oliver! film) singing As Long As He Needs Me.'
Another said: 'How mean excluding her. For what purpose?'
A third penned: 'Imagine not showing this! Oh my gosh Shani Wallis is 92 and she's still got it what a powerhouse.'
A fourth agreed: 'My thoughts exactly she should have OPENED or closed THE MAIN SHOW. Not #BGT2026 demoting a singing & acting icon like Shani Wallis to BGT Unseen.
'She freaking played Nancy in Oliver on stage and the #Oscars winning musical Oliver! Simon Cowell shame on you.'
A fifth commented:'Why was Shani Wallis demoted to the unseen auditions on You Tube?
'She is an icon and sang brilliantly. Such an amazing moment seeing her back on stage.'
While a sixth shared:'Shani Wallis going on BGT was actually so beautiful. Why did it not make the main cut!'
Oliver! starred Mark Lester in the title role, with Oliver Reed as Bill Sikes, Ron Moody as Fagin and Jack Wild as the Artful Dodger.
Shani previously described Oliver Reed, who was notorious for his alcoholism, as 'very frightening', but stressed that he 'never actually hurt me.'
She said: 'The truth is, I had little to nothing to do with Oliver Reed off-set; his life I believe was complicated.'
Shani performed As Long As He Needs Me - a song she memorably sang as Nancy in the 1968 film Oliver!
However, despite the monumental success of Oliver, Shani did not go onto have the career that she would have liked.
She previously said: 'No, but that was my fault. When I came back to America, I had offers to do what became a very famous series on television, The Brady Bunch. I didn't want to do that.
'I wanted to do movies. But then movie musicals like Doctor Dolittle flopped and they decided not to make any more, which was a big blow.
'I went back into theatre and nightclubs. If I'd stayed in the UK after Oliver!, I'd probably still be working hard. But I had an ultimatum from my husband.'
She said: 'Bernie said: "If you want to be with me, I won't live anywhere but California."'
Other key cast members included Harry Secombe as Mr. Bumble and Joseph O'Conor as Mr. Brownlow.
At the 1968 Academy Awards, the film won six gongs including Best Picture and Best Director.
