What is this advert, in the uk, where a man and a woman build a kind of car in cardboard?

I love the song in that advert and I'm looking for it, I don't even remember what it's for. A man and a woman, in another two women i think, are building things in cardboard. the song is sung by a woman.

Sounds like the Orange advert. The song is awful, I have to hit mute.
