Binge watching since Sat, Can't get anything else done!!

OMG!! I usually hate the campy novellas that I grew up watching mis abuelos watching (yes, my grandfaher too!) but I am obsessed with Celia!!! I love everything about it. But please, someone, tell me who is singing "Buche y Pluma Na' Ma" in Episode 16?? I have been searching everywhere for that perfect rendition but I cannot find it. La India comes close, but that's not it. Please help!!
