Shane Grove delivers mail in North Central Ohio five days a week. The other days, he's writing songs that end up in the hands of Tanya Tucker, David Allen Coe, and Eddie Montgomery — and he's got the stories to prove it, including the one about writing "A Million Reasons" on a notepad while walking around downtown Cincinnati, waiting to find out if David Allen Coe's federal court hearing had gone his way.

Sarah sits down with Shane to trace a career that swings from a teenage stint as a background inmate in Shawshank Redemption to co-writing "Higher" for a Tucker/Montgomery duet, to his 900-episode paranormal podcast From the Shadows. Along the way: the real story behind Coe's on-the-fly rearrangement of "Corner of Cash and Co.," a late-night text thread with Tanya Tucker, Brandi Carlile, Miley Cyrus and Elton John, and why Shane thinks showing up — again and again, for decades — is the whole game.
