The Mamma Mia star learned the dulcimer during the pandemic, and paid homage to one of her heroes with a cover of California

Actor and singer Amanda Seyfried has set a studio audience and its presenter – and now the internet – off by skilfully covering a Joni Mitchell song on the dulcimer. The dulcimer. That’s right. The wooden string instrument, played across the lap, which originated in the Appalachian Mountains in the 19th century.

The actor learned how to play the instrument during the pandemic, and her rendition is uncannily like the original.
