I am sitting here in wonder. My brother has never heard of the song “Let It Go”. He’s firmly refusing to believe it’s famous. I’m refusing to believe that he hasn’t heard it. I’ve sung it for him in English, French and Dutch (that’s how I roll). Very reluctantly, he has conceded that the fact that the version he looked at on YouTube has 450 million likes might mean that some other people are aware of this obscure number.
