Good Days, Bad Days

This Sunday afternoon, much in need of a little musical refreshment, I played 'Blue' by Lucinda Williams- a collective favourite tune of both Spouse and myself.
I quite reasonably expected a reaction from Spouse other than bewilderment and a vague sense of recognition, and other than the strange query: who is this? What song? as our beloved singer warbled what ought to have been comfortably familiar.
Spouse has, at least as long as I have known him, demonstrated an uncanny, consistent ability to recognise a song from the first note or two, and the lack of such is a wholly terrifying prospect.
