Two friends on a skiing holiday both have a song stuck in their head, but neither can remember the name of the group who sings it - sound familiar?

They sing it around the resort together as they ski, but fail to come up with the answer.

Eventually, one of them suggests making a video call on 4G to a friend who knows all about music. It turns out that their friend recognises the song and hums along with them.

The bad news is that he doesn't remember the name of the artist either.

It would be great to be able to count on friends as much as Orange 4G.
