BRITAIN'S Got Talent winner George Sampson was back on the programme tonight with a fabulous new dance routine.

The Birchwood Community High School pupil, who is currently studying for his GCSEs, was a guest star on the fourth semi-final programme.

Dancing to Pink Floyd's Another Brick in the Wall, a taller and more confident George thrilled the studio audience with a stunning routine.

Speaking to Ant and Dec after the show, George said: "It's amazing to be back, it's been such a good year."

George said he thought the acts on this year's show were really good.

Judge Simon Cowell said afterwards: "How good was George."

Winner of tonight's semi-final was Julian Smith, a 39-year-old saxophonist.

Judges had to choose the second act to go through between Two Grand - singing grandfather and grandaughter act John Neill and Sally Lux and 12-year-old singer Callum Francis.

Both Simon and Amanda Holden voted for Two Grand to go through to Saturday's final.
