The first episode of the talent show saw a variety of different acts performing including an eight-year-old comedian and a pair of mind readers, who shocked the crowd with their captivating performance.

The show kicked off with Ned, an eight-year-old comedian from Maidstone, who roasted the judges by comparing Amanda Holden to a talking dog.

His comedy act was met with a round of applause from the audience for his sheer bravery and he sailed through to the next round.

The launch of the 11th series saw Simon Cowell push the golden buzzer for the first time of the series sending 15-year-old superstar Sarah from Milton Keynes straight through to the live semi-finals.

The judges and audience alike were left in awe of Sarah's performance of the 'Dreamgirls' hit, 'And I Am Telling You'.

Initially, the judges were skeptical about the brave song choice but Sarah defied their worries and insisted it was the song most suitable to show off her range.

Alesha Dixon said: "A girl of your age shouldn't have a voice that talented. I didn't want to press the golden buzzer because I wanted Simon to do it."

Sarah's family stormed the stage after she got the golden buzzer.

Another act had an emotional impact on both the audience and the judges. 'The Missing Persons Choir', a group of people who have come together over their shared struggle of having missing family members, performed 'I Miss You'.

The choir's performance brought tears to the audience members as pictures of their loved ones were projected on the screen behind them.

With a standing ovation from the judges and the audience, the choir received four yeses.

Another four yeses went to mind readers D and A who left the judges stunned as they used both Simon and Amanda as part of their mind reading act.

An act of 'Doga' - yoga which incorporates a dog - had three of the four judges as well as presenter Dec Donnelly on stage with their own pooches.

However, the performance - which got three yeses - ended in shambles as some of the dog's urinated on stage and in David Walliam's shoes, leaving the audience wiping happy tears from their faces.

Like every series, there are acts that simply don't cut it. Painter and decorator Jim's unusual four-act performance saw him change costumes and papier-mâché masks and dance around the stage. However, he missed out on a place in the next round.

'Britain's Got Talent' continues next weekend.
