"Opening our Main Stage this year will be the sublime vocalist and superb songwriter, musician and storyteller Kitty Macfarlane with her band.

"For our Acorn stage we are over the moon to announce the original, inventive and thoroughly entertaining duo The Bookshop Band.

"And we are delighted once again to have the London Youth Folk Ensemble opening our second stage."

Sam Sweeney tweeted: "Delighted to be playing @FolkByTheOak 2020 - Get your tickets.

"The line up is the best I've seen this summer and it's a wonderful day out. Come and hear me and my band play the new album live!"

The latest additions join Seasick Steve, Richard Thompson and Kate Rusby on the bill.
