Britain’s Got Talent 2012: Ryan O’Shaughnessy’s No Name love letter melts hearts

Saturday's edition of Britain's Got Talent 2012 ended on a high with 19-year-old Dubliner Ryan O'Shaughnessy's self-penned song 'No Name' about his love for his friend.

It was a night of great acts, but they certainly saved the best for last with Ryan O'Shaughnessy.

He revealed to the judges Simon Cowell, David Walliams and Alesha Dixon that he'd written his song, 'No Name' about a friend that he's been in love with for years.

Simon Cowell and David Walliams tried to push Ryan for the girl's name, but he resisted, with Ant and Dec's support from the wings.

The amazing track captured the hearts of the judges and the audience.

David Walliams exclaimed: "I can't believe she won't go out with you! That's the most beautiful song I've ever heard."

Simon Cowell called it "astonishing" and must have been seeing pound signs.

Alesha Dixon said the tune was "sweet and sincere".

Ryan won over Twitter too, with #noname becoming the top trend. "He's Irish" was also trending.

Another act who impressed us and Twitter was Ashley Elliott.

David Walliams called him the "one man xylophone playing One Direction." Ha! Xylophone trended on Twitter. Obvs.

The Mend surprised us with their fantastic version of 'Sitting On the Dock of the Bay'. They mixed it up with rapping and their own flavour, and got Twitter all in a flutter.

East 17 was also trending. Coincidence? We think not.

Simon Cowell tweeted: "I thought The Mend sounded great on @GotTalent tonight and Ryan, has it worked?"

Twist and Pulse from a previous series were back, but this time they didn't take to the stage.

They were there to support the dance collective they put together, Twist and Pulse Dance Company.

The group reminded us of Diversity and gave a funny and impressive group performance.

Beatrix Von Bourbon was one act we thoroughly enjoyed but can't really see performing for the Queen at the Royal Variety Performance. The burlesque artist certainly impressed David and Simon.

Acts that didn't fare so well with the judges included Deja Vu, who introduced themselves as the "older Little Mix" and alas didn't make it through.

Which act impressed you the most this weekend?
