In 2021 Barry Gibb recorded Greenfields: The Gibb Brothers Songbook, Vol.1
, a collection of Bee Gees songs reinvented as country duets. Gillian Welch and Dave Rawlings first came to his attention via the O Brother Where Art Thou?
soundtrack. Gibb linked up with the country folk duo to cover "Butterfly"
for the album.
"Dave Rawlings and Gillian Welch didn't want to do a song that was well-known, because that's their nature as an act - they're very pure," Gibb told Entertainment Weekly
. "They leapt all over 'Butterfly,' which was out in 1966. It just worked out wonderful."
