A group of male Oxford University students have recorded an entertaining music video of them belting out a medley of hits from Frozen while dressed as the characters.

Out of the Blue, an all-male acapella group at the top university, performed a medley of tunes from the Disney film and its smash hit sequel to raise money for charity.

Every year the boys release a Christmas charity single that is viewed millions of times online, and their newest clip features the blue-suited boys performing Let It Go, Do You Want To Build A Snowman and Into the Unknown.

The video shows the boys in many of Oxford's iconic locations, including the Bodleian library and the Bridge of Sighs, belting out the children's film hits to raise money for children with terminal diseases.

The singing group are hoping to raise as much money as possible for Helen & Douglas House, the oldest children's hospice in the world.

Out of the Blue president Rory Naylor, 20, said: 'We're all around university age so we were the right age when the original Frozen came out.

'Obviously we fell in love with the soundtrack as it's incredible.

'We saw the sequel was coming out this year and so it works in terms of marketability.

'We all went as a group to the cinema to watch Frozen 2 and half of us cried. We loved the songs so it made a lot of sense to cover them this year.'

Rory, a medicine student in his third year, said the all-male choir is 'actually more competitive to get into the group than to get into Oxford University itself.'

He said: 'It's so competitive.

'It's a three-round audition process over the first week of term.

'We then have a secret initiation process and then they're in.

'The initiation is actually quite tame and cute, but it's very secret.'

Choreography is also involved for the lengthy routine throughout the video. Most of the members wear suits throughout while others wear Frozen character outfits

After the group is formed every year, the new members' first gig is for Helen & Douglas House.

Rory, from Knighton in Wales, said: 'It's the highlight of the year for me. All of the proceeds from this single go to Helen & Douglas House.

'Kids dance and move around, they're always really cheerful. It's lovely.'

The group has even been featured in talent shows such as Britain's Got Talent but has different members each year

Out of the Blue, which has been featured on Britain's Got Talent and Pitch Battle, has donated over £100,000 to the charity over the last five years.

All proceeds go to the charity, with the boys collecting with buckets in shows throughout the year.

The group is also notable for providing a safe space for gay, bi, queer and trans men at Oxford University.

Rory said: 'As a queer man myself, it's important to me as president to continue representing the community and making content that would show us off a bit.

'A lot of modern acapella is quite serious and Out of the Blue tries to push the boundaries in terms of being an Oxford University society.

'We don't want to come across as nerdy Oxford students.

'We want to come across as accepting people regardless of how they identify, regardless of background. We try to be as inclusive and as fun as possible.'

The Frozen medley has already received a lot of positive responses, and the Out of the Blue president said he expects to hear feedback from the people who made the films.

Rory said: 'We've got a contact with Chris Burke who directed Frozen and Frozen 2 so we're waiting to hear what he thinks.

'If Idina Menzel, who sings Elsa's parts, saw it, now that would be the dream.'
