May I give you a late Christmas present? Toward the end of Impromptus last Thursday, I mentioned Mariah Carey’s 1994 hit, “All I Want for Christmas Is You.” I told a little anecdote concerning it and said that the song had already achieved classic status (or something quite like it).

A reader sent me this video, of the way some members of the Royal Navy have treated this song. I cannot say anything about the war-fighting prowess of the men and women aboard HMS Ocean, although the Libyan operation seems to have gone satisfactorily. I can say that their video put a smile on my face.

Are they the most entertaining sailors since the cut-ups in South Pacific?
