John Hartford was a multi-instrumentalist, voice over actor, steamboat captain, and folk composer. He is one of the finest song writers in the folk style that I've ever heard. I don't know why he isn't more famous than he is.
Now, the mystery is that there is very little information on the vast internet about the featured song and the album that it comes from, Gentle On My Mind and Other Originals. Of course, Google searches for Gentle On My Mind return hundreds of references to Glen Campbell's smash hit cover of Hartford's song of the same name. But this wonderful album, being currently out of print, is only available on vinyl and is not even linked at all on Hartford's Wikipedia page. AllMusic provides the only review I could find, but the review is odd (e.g., Mouth to Mouth is referred to as a "chilling" song. Uh, I don't quite hear "chilling". Do you?)
Internet, you have disappointed me. I thought you knew everything.
Here's the bonus: There are two songs on Gentle On My Mind that match this week's theme. The other is the beautiful The Tall Tall Grass. Enjoy.
