A group of dancing dads and grandads provided the biggest surprise in the fourth episode of series 9 of Britain’s Got Talent.

Old Men Grooving, five balding blokes wearing woolly jumpers, managed to trick everyone including Simon Cowell by starting slow but then erupting into a mash up of hit songs including James Brown’s Get Up and Eminem’s The Real Slim Shady.

Everyone loved the grooving old men.

And were generally pretty surprised by them.

BGT is all about entertainment right?

Judge David Walliams told the dance group: “You made dad dancing cool.”

And Simon Cowell added: “I was not expecting that but you tricked me.

“You lot, I could watch you all night. You really proved age is nothing but a number.”

Also vying for the star of the show position was 12-year-old singing sensation Maia Gough, who rounded off the proceedings with an impressive rendition of Whitney Houston’s I Have Nothing.

A standing ovation for Maia (Tom Dymond/PA)

Some compared her to Charlotte Church. Well as far as she’s young, Welsh, and has a good pair of lungs on her.

Others were feeling a bit more cynical.

Saturday’s show also proved everyone loves Disney, however it’s sung.

Aaron Marshall, 20, proved most people love Let It Go from Frozen, even if you sing it in a heavy metal style. He got the audience singing along and even got a standing ovation.

But judge Amanda Holden disagreed with the audience and, comparing him to Satan, gave him a “big fat cold icy frozen no”.

Viewers were split. Some diagreed with the audience…

But others loved it.

More Disney followed, and viewers loved sickly sweet Disney-themed girl group Misstasia, who sang Part Of Your World from The Little Mermaid.

Cinderella, Ariel, Bella and Snow White, according to Amanda Holden (Tom Dymond/PA)

Some people (Amanda Holden) seemed to think they were actually Disney princesses, and the judge said the girls looked like Cinderella, Ariel, Belle and Snow White.

There were those who had goosebumps from the rendition of the Disney classic.

But others found the group’s effort a bit too much.

Simon Cowell said: “This is either a really good idea or the most annoying girl group in history.”

Funny moments included entertainer Peter Lambert not being able to get on his unicycle backstage.

It didn’t go unnoticed.

Yep, definitely not, but he did get through.

The Twitterati were also asking the question – was 15-year-old dancer Jonathan Lutwyche from Gibraltar actually Billy Elliot?

Is that you Billy? (Tom Dymond/PA)

Pssst..Billy Elliot isn’t real.

He was even dubbed “The Gibraltan Billy Elliot”. Considering it was a compliment, Jonathan might overlook the fact “Gibraltan” is not a word – the correct term is Gibraltese or Gibraltarian.

And people loved Jonathan’s story. But still only really managed to compare him to Billy Elliot

Also going down well with the audience was the dad and his three sons in a singing group.

The Neales looked like they already have some female fans.

And people loved their sweet story too.

If you missed it: The dad had a heart attack, so re-evaluated his life and here we are today.

Even Simon Cowell went all gooey.

Dad and daughter drumming group Blast had a blast themselves even if no one else did. They got four nos, as did George Vernon bizarrely singing to his mannequin.

This hairdressing act didn’t get through either.

BGT
Interesting… (Tom Dymond/PA)

Viewers seemed happy with the offering, but disappointed with the lack of any golden buzzer acts.
