What song does this christmas video go to?

In the video, there is a family all sitting around in the living room. there watching the queen speech on tele and the dad or grandad looks really bored. then the tv breaks and the son (who is about 19) goes and smacks the top of the tele. the tele comes back on but instead of the queens speech, the video to this song comes on. its a man singing and there's two women either side of him who are also singing. it says something about ''mama will do the best she can, and she can'' then he does this weird action with his hands which looks a bit like the mexican wave. its really cringey and i think the song has something to do with the queen speech. its been bugging me since last christmas and its such a cringey song and i really want to hear it. thanks x
