Fiona and Dave and Rodney and Brenda
I dare say some of my readers (Phil, perhaps) remember a folk duo from back in the 1970s called Therapy, comprising Fiona Simpson and Dave Shannon. They appeared a few times in Durham while I was a student: indeed they recorded part of Bringing The House Down there. Their recordings never made it to CD (but I have the means to play vinyl) and I lost track of them after leaving college. There isn't much about them on the Internet, even, though I note from this that Dave Shannon recently appeared at my old stamping ground in Poynton.
They did some self-penned material, latterly mainly humorous (though they started out as a trio doing serious material of their own), and a lot of excellent cover versions (including the best version of Ian Tyson's Someday Soon I've ever heard).
I recently found a link online to a piece I hadn't heard before. I have just succeeded in acquiring the vinyl album from which it is taken, but here is the mp3 for your edification. Harmless fun, and a blast from the past.
