Watch Wynona cover Billie Eilish live in session for Best Fit

Speaking to Best Fit about their choice of cover, Wynona's Natalie says, "We saw her at Glastonbury and I’m a big Billie fan so I think it just made sense to take one of her songs and put a little bit of a twist on it with live guitars, a live drummer - more of a guitar version of what I'd imagine that song would be if we would take it and change it."

The band's Rich adds, "I'm probably not as big a Billie fan, but you [Natalie] kind of coaxed me along to go and see her and I was really blown away. I thought she was great, and I think we've always identified with her and Finneas because we’ve been making music in our room the same way for years. We've always really appreciated what they do.

Wynona's latest single "My Mind is Melting (Cool Like You)" arrived in June. They'll play London's Source on 27 October.
