The last round of auditions for Britain’s Got Talent had five acts that made it through to the top 40 for the live semi-finals.

But it was Jules and Matisse – especially Matisse – who won the hearts of the audience and judges.

Matisse is a seven-year-old Border Collie that, Simon Cowell says, “is the smartest dog I’ve ever seen” (and that’s without any gadgets in its mouth). Jules is the woman who loves Matisse and trained him.

“We’re going to perform a dog dance,” Jules told the judges. “But I can’t dance.”

Uh-oh.

“We’ve entered because I’ve always thought Matisse is special.”

Special enough to win, like Ashleigh and Pudsey in 2012?

Their act was Jules playing the evil dog catcher, with Matisse dancing away from her. The audience loved them and the all the judges were on their feet at the end.

“The relationship between the two of you reminds me of me and Simon,” said David Walliams. “It was joyous. Very clever routine.”

“I felt like I was nine years old again,” Amanda Holden smiled. “It was a faultless story and routine.”

“It was brilliant,” added Alesha Dixon.

And Jules and Matisse will perform again in the live semi-finals.

So will family act the Kanneh Masons, six brothers and sisters who perform classical music on piano, cello and violins.

“We thought, ‘Why not form a group and see what happens,’ they told the judges.

What happened is everyone loved them.

Austrian magician Michael Late worked enough magic to get through to the semis, too. So did impressionist Andrew Flemming, despite his angry rant. More on him here.

Six-piece girl band The Honeybuns were the last act to audition for 2015 – the lucky last, as they also made it through to the semis.

“We met at Weight Watchers. As you can tell, that didn’t really work,” they said. Then they launched into It’s Raining Men.

“It’s really my anthem, that song,” David told the girls.

“It was fun,” Simon said. “I like your personalities. But I kind of feel this is more cruise ship entertainment.”

“Don’t know if we’d fit on a cruise ship!” laughed the Honeybuns.

But there’s room for them in the semis.

“This is going to be the craziest finals we’ve ever done,” said Simon.

The Britain’s Got Talent Live Semi-Finals start on ITV, Monday, May 25, 7.30pm.
