If you think university doesn’t come with any side of fun, then think again. This all-male acapella group in Oxford, in the U.K. – made up of students from Oxford University and Oxford Brookes University, has had a bit of extra fun lately with pop-star Shakira tweeting her appreciation of their latest you-tube video and song – a medley of some her music. The group, called Out of the Blue, performed the video as a charity project with donations from purchases of the song going to the Helen & Douglas House, a children’s hospice in Oxford.

Out of the Blue performs regularly in Oxford, and the group have also achieved a bit of international fame having taken to the stage in Spain, Scandinavia, Japan, Hong Kong, the U.S., and most recently, in Lucknow – India. In the U.K. they are featured at the Edinburgh Fringe Festival, the world’s largest arts festival (and a not-to-be-missed-experience for anyone studying in the U.K.).
