Britain's Got Talent 2015 live semi-final one: Entity Allstars and Cor Glanaethwy make final

Entity Allstars were judge Alesha Dixon's Golden Buzzer act this series

Entity Allstars made it through to the Britain's Got Talent final

A Welsh choir and youth dance group were the first acts to make it through to the Britain's Got Talent final last night.

Cor Glanaethwy won the public vote to zoom automatically into Sunday night's grand show before judges Simon Cowell, Amanda Holden, David Walliams and Alesha Dixon chose their favourite from the other top three contenders.

Walliams gave cute 12-year-old Henry Gallagher his vote but the rest of the panel opted to save Harry Potter-inspired Entity Allstars instead. Dixon had used her Golden Buzzer on the Essex collective earlier in the series, sending them straight to the live semis.

Nine acts competed for places in the final, with Mitch and Cally the Wonderdog coming fifth and breaking the world record for most balloons popped by a dog (niche, yes, but congrats to them anyway).

Latino singer Ricky Martin performed new song "Mr Put-It-Down" while hosts Ant and Dec made light of the evacuation of the Britain's Got Talent studio last week.

A World War II bomb was discovered near Wembley Stadium and later safely detonated. "Hitler tried to stop us and for the second time we defeated Hitler," Cowell joked.

The Britain's Got Talent live semi-finals continue every night this week, with magician Michael Late, dance group Old Men Grooving and dog act Jules O'Dwyer and Matisse among the acts taking to the stage tonight.

The big prize is £250,000 in cash and the opportunity to appear at the Royal Variety Performance.

Tune in to Britain's Got Talent at 7.30pm on ITV, with the results show following at 9.30pm.
