Surprisingly, I haven't heard "Merry Christmas, Darling" by The Carpenters on the radio yet this year. I can't remember the last year I hadn't heard it at least once by December 11. If radio stations are phasing it out due to the song's age or a decline in popularity, that's a shame. Karen Carpenter sings it with such convincing warmth and longing. It's no accident that the public took to it and that radio stations have played it frequently at this time of year since 1970.
Hopefully, radio stations with appropriate formats for it will play it on Christmas Eve, at least. That's when the song takes place, so it would be considerate to let the audience hear it at least once that night.
