Jill Sobule (the original - and better - "I Kissed A Girl", "Supermodel") did a similar thing when she had surgery for an essential tremor.
Singer-songwriter Jill Sobule is known to take audiences on emotional journeys through her music. She plays at the Little next week.

I also saw a story about a violinist having similar surgery. And one story about someone having a tumor removed where they'd remove a layer, then probe the brain to see if they could remove more w/o affecting function.
