I saw every episode of the Monkees repeatedly when I was a little girl (7 years old? I think I had a tiny crush on Mike Nesmith back then. Or the closest I ever came to a crush on a guy - outside of Gregory Peck and Kermit the Frog *don't judge*). But I don't recall ever having seen this; I could be wrong.

In hindsight, having a(faux) "mainstream pop band" sing a Christmas song entire in Spanish seems at least a couple of decades or more ahead of it's time.
