They both hope that the song he's prepared will blow the judges away.

Well, I'm singing 'Valerie' today, by Amy Winehouse, and I'm just singing it because it's one of my favourite songs to sing.

I sing it in different family occasions

I sing it in different family occasions for, like, weddings and parties and different things.

And my granddad really loves this song so, whenever I sing it, it makes him happy.

So it's a big day for you, today.

Yep.

This could be the big break.

Exactly.

The first day of the rest of your life.

Dec: Is this mum? Karen: That's me. Ant: Look at that face, he's not worried.

Dec: Hiya, mum. You alright? Karen: That's me. Ant: Look at that face, he's not worried.

Dec: Hiya, mum. You alright? Karen: Yeah, fine. Ant: Look at that face, he's not worried.

Dec: Hiya, mum. You alright? Karen: Yeah, fine. Ant: He's not worried.

Dec: Hiya, mum. You alright? Ant: He's not worried.

Shaheen.

Well, you have just shown that Wales has got talent.

Thank you.

Doesn't happen to me very often,

Doesn't happen to me very often, but I get... I do the goosebump test.

I got it with Paul Potts,

I got it with George Sampson,

and I got it with you.

Piers, yes or no?

It's a definite 'yes' from me, Shaheen.

Oh, it's a no-brainer.

Yes!

Thank you.

Shaking

I know, I'm shaking, I'm really nervous.

Shaheen,

you just got three very large yesses.

Thank you!

Love him...

Well done!

Thank you.

Well done, that was amazing.

That's a really hard song to sing, that. I mean really hard.

What did it feel like at the end, there? Everybody stood up, the three judges were on their feet.

It was (just) amazing.

I never knew I could make somebody do that.

It's just... ah. Can't describe it – words can't describe it.

It was really good.
