Report: Show Four
In the final show of the series Graham Norton presented another seven acts to the nation, battling out with last week's winner to be the winner of £10,000.
First we had what Graham called a 'question of balance', with Lilia Stepanova going up against 8 Storey.
Dave liked both the acts, but had his favourite. "A great start. Lilia, you're very bendy, aren't you? Great act. I'm sure you're a star in America. But for me 8 Storey were absolutely brilliant. Everything was right, the image the music, the routine, the way that the elements came together with the girls - I think you'll achieve every ambition that you have."
The armchair judges agreed, with 79 per cent voting for Eight Storey.
Next up were two acts that Graham dubbed "Twisted instruments" with the Red Hot Chilli Pipers taking on Stringfever.
"I think that Stringfever are talented musicians. I think introduce some stand up comedy into your act and it will be even better," said Max. "With the Red Hot Chilli Pipers I can see them opening for Billy Connolly. It's a unique musical combination." It was a close vote, with 51 per cent of the armchair judges voting for the Red Hot Chilli Pipers.
The third showdown Graham called 'bounce vs. balance', with Joao Santos taking on Swe Bounce.
The bouncing Swedes - I loved the music and I admired the skill but for me it was just a bit of dancing and a few somersaults. It wasn't a complete act," said Dave. "With Joao, I spent the whole act growing 'wow'. It was phenomenal."
75 per cent of the vote put Joao Santos through.
The final showdown of the night saw last week's champs, Libera taking on Human Slinky.
"I was the first person to bring you to London. You're still a great act," said Chuck. Of Libera he said, "The act was good but not great for me." The public agreed, with 67 per cent putting the Human Slinky through.
In the results show, our four top acts of the evening came back to face a public phone vote. The votes frozen, it was announced that Red Hot Chilli Pipers would face the Human Slinky in the head-to-head. After both acts had performed once more, the time had come for Graham to announce the winner. An ecstatic Red Hot Chilli Pipers walked away with the £10,000 prize.
