We didn't need it, but someone figured out how to make it anyway:

To create “Noche Buena y Navidad,” after rewriting the song, Baquiero brought in Chilean vocalist Leyla Hoyle to sing it in Spanish while mimicking the pitch and phrasings of the original. The vocal stems were then sent to SoundLabs, which ran the vocals through its “Brenda Lee” AI vocal model that was trained on hours of the singer’s isolated vocal stems, including the original “Rockin’ Around the Christmas Tree.” Baquiero then mixed the vocal into the original music elements of the track. The goal was to make it sound like 13-year old Lee was singing—and it does, but it also sounds a little uncanny.

The project was completed with a full sign-on from Lee, who is now 79 years old. “Throughout my career, I performed and recorded many songs in different languages, but I never recorded ‘Rockin’ in Spanish, which I would have loved to do,” Lee said in a press release. “To have this out now is pretty incredible, and I’m happy to introduce the song to fans in a new way.”

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
