More than a year ago, old friends and Drag City labelmates Bill Callahan and Bonnie ‘Prince’ Billy started covering songs together. Over the course of the pandemic, Callahan and Will Oldham teamed up to release a couple of albums’ worth of covers of other people’s songs — some obscure, some super-famous. On each of those covers, the group had a different collaborator, usually drawn from the ranks of the Drag City roster. It’s been a while since the two of them released their last cover, a version of John Prine’s “She Is My Everything” that featured Sir Richard Bishop. If that had been the ending, it would’ve been a fitting one. But now, the whole Callahan/Oldham project is back up and running again.
