Actually, it's Mrs Santa....Santa made me listen to it, on CD, at an ungodly hour, when we'd just got in from a festival. "You've got to listen to this". Once heard, I had to sing it.
I have "folk processed" the chorus, by missing out "now" after "swim with me", until the final chorus. It wasn't done deliberately, just how I remembered it walking the dog the next morning, and then it stuck. I have since sought, and received Nicole's permission. She's very relaxed about arrangements of her songs, and happy that people want to sing them.

I've alwaye found that it makes quite an impression.
