I Can Haz Earworm?

Mom and I went to see Carmen a week or so ago and a bit I had never paid much attention to before got stuck in my head. I'm going to pass it on before I'm reduced to singing my two go-to earworm replacements.

The only video I could find of it is this wonderful silent film with music over it. Remember Gloria Swanson in Sunset Boulevard? "We had faces then."

You're welcome.

What is your go-to earworm exterminator?
