Out of the Blue (OOTB), Oxford University’s all-male a cappella group, has released a cover of Mariah Carey’s holiday hit “All I Want for Christmas Is You” and a music video filmed at the historic school’s Bodleian Library and Divinity School.
Proceeds from purchases of the single will be donated to the Helen & Douglas House Hospice for Children and Young Adults.
The group claims its cover of Shakira’s “Hips Don’t Lie,” released over the summer, raised more than £10,000 ($15,700) for the charity. It also boasts more than 5.1 million views so far—thanks to some Twitter encouragement from the Colombian pop star herself.
