When Immi Davis stepped onto the Britain’s Got Talent stage, she looked like a fairly shy nine-year-old.

She had been watching the show since she was five and had always wanted the chance to stand on that stage herself.

Now that the opportunity had finally arrived, Simon Cowell wanted to know what she planned to sing.

Immi chose “I Put a Spell on You.”

It was an unusually mature and demanding song for someone her age.

So Simon naturally asked why she had picked it.

Her answer was wonderfully simple:

She had been practicing it.

The judges smiled.

Then the music began — and the mood changed completely.

The Voice Didn’t Match the Introduction

Only moments earlier, Immi had seemed like a quiet schoolgirl answering Simon’s questions.

Once she started singing, that impression disappeared.

Her voice had a depth and character that seemed surprising for someone only nine years old.

The official BGT description said they simply were not expecting that kind of voice to come from someone so young.

As the song continued, Immi became increasingly confident.

The performance grew stronger.

The audience reacted louder.

And the judges began exchanging looks as though they were trying to process what they were hearing.

The contrast between Immi before and during the song became one of the most memorable parts of the audition.

Alesha Dixon specifically commented on how dramatically Immi seemed to transform once she started performing.

Simon was equally amazed and described what she had done as extraordinary.

By the end of the song, the judges and audience were on their feet.

There was little suspense when voting time arrived.

Immi received a yes from all four judges.

Her audition had taken her from a childhood dream of appearing on BGT to a real place in the competition.

And she wasn’t finished.

Immi later came back during the live semifinals and performed “River” by Bishop Briggs.

Once again, the focus was on the contrast between her age and the power of her voice.

ITV described her as a tiny singer with a giant voice.

She did not ultimately advance to the Grand Final, but reaching the live semifinals at only nine years old was already a remarkable achievement.

Perhaps the most charming part of Immi’s audition happens before she even sings.

Simon asks why she chose such a difficult song.

She doesn’t give a dramatic explanation.

She simply says she has been practicing it.

Then she proves exactly what all that practice had produced.

A shy nine-year-old walked onto the stage.

A few minutes later, the whole room was standing.
