It’s been a fine week of talent but Thursday evening saw the last Britain’s Got Talent semi-final of 2012 unfold – but did show bosses save the best for last?

First to take to the BGT stage was basketball stunt group Face Team, who, let’s face it, were pretty spectacular. The lads jumped, they bounced, they slam-dunked: it’s difficult to do it justice with words. Watch the routine here.

Alesha Dixon, gave them a standing ovation, and said: “I thought that was an incredible start to show. The choreography was brilliant, so much going on at the same time…the music was good… it was good to see an act so physical….. you should be proud.”

Next up, well this one wasn’t so energetic. Glaswegian electro musician Greig Stuart played a laser harp mashup but sadly hit a bum note with the judges.

Simon Cowell told him: “The end was ok with the dancers but at the beginning it sounded like someone was treading on a cat - you hit some bum notes…you need a lot more practice.” Do you agree? Watch Greig’s performance here.

Third act, Billy George, sent temperatures soaring with his sexy cyr whell performance to Mama Do the Hump by the Rizzle Kicks. What’s cyr wheel we hear you cry? Watch and find out. It’s pretty impressive, especially considering Billy performed with no top on showing off a rippling six pack – much to the delight of Amanda Holden, who told him: “You are kind of like the Peter Pan of the hoop world and I believe! I believe!”

From wheely good, to wheely potty: next up was Martyn Crofts, the dalek impersonator who was wearing a glittering pot on his head. Need we say more?

Simon said: “That was arguably the most stupid act I’ve ever seen on the show... I’m urging Doctor Who fans not to put you through…” Yikes! Take a look.

Next, it was time for some light laughter with 16-year-old comedian Callum Oakley who joked about his mum buying cheap toilet paper. It is funnier than it sounds. Check out the cheeky chap in action here.

Fellow comedian David delighted the Liverpudlian by telling him: “Callum that was incredibly good. I still can’t believe you’re 16. You’ve got a very good presence and whatever happens tonight, you are going to be a comedy star of the future.”

Next act hoping for a place in the final was Hope Murphy. Also 16, Hope, from Essex wowed with a beautiful rendition of Forever Young which saw Simon Cowell dub her a young Adele.

Watch her performance now – do you think she could be the next big thing in the charts?

Strictly Wheels delighted with their fun-filled routine to Olly Murs Dance With Me, but Alesha and Amanda, although impressed, felt the dancing duo’s audition performance was better.

Amanda said: “I felt a little bit disappointed and underwhelmed tonight. You did a good job but I was just a little but underwhelmed.”

Did you like? Watch them now.

Next to cause a splash, was synchronised swimming troupe Aquabatique.

The talented water babes performed a wonderful water routine (in a tank outside the studio) to a James Bond medley.

The judges loved it and David Walliams told them: “That was all the things I love: swimming, James Bond and skimpy gold outfits.”

Dive in and watch the young ladies in action here.

Last, but by no means least, it was Ryan O’Shaugnhessy’s turn to take to the stage. Ryan tugged at all her heart strings during the auditions when he performed self-penned track No Name – a song about a friend he fancied.

Sadly, he admitted No Name said no to being his girlfriend, but that didn’t stop the Irish student putting his heart and soul into another emotional track in the semi-final – this time called First Kiss. Watch it, it makes us want to cry, in a good way.

Simon told him “I wouldn’t worry about her cause you are going to get so much action after this!” Mr Cowell!

He continued: “Do you know what I like about you? You are believable. I think you are a brilliant songwriter and you are also a brilliant singer. Maybe you could be the dark horse of this competition.”

Well the dark horse certainly has a lot of fans out there as Ryan won the public vote through to the final, much to his shock and delight.

Joining him? It was down to Aquabatique and Billy George but Aquabatique won the judges vote and their place in the BGT 2012 final this Saturday.

Who else is through? Check out the fine list of talent here and tune in on Saturday night from seven to see who is going to be crowned Britain’s Got Talent champ 2012.
