This is the only Christmas song released during my record-buying lifetime which sounds like an instant Christmas classic; as though you must have heard it before, probably performed by Brenda Lee or the Rockettes. But no: it’s just a properly good Christmas song from Mariah Carey.

(Actually it’s not the only one – Christmas Time (Don’t Let The Bells End), which we had last year, is an utterly authentic glam rock Christmas hit.)
