So, I can't remember stuff like which songs got played, but I do remember being particularly pleased at two or three of the choices. And, er, Slowly But Surely may have been one of them. It's probably my most recently acquired favourite track of hers - the LP version is just immaculate (the kind of thing that might have got into the Top Ten in the eighties maybe) but I prefer the demo version on the b side of On The Fire. Both are amazing.
Anyway, I didn't know it was a cover version until about two weeks ago. Here's the original. Yet another upset for my tending to prefer whichever version you hear first theory (I may scrap that theory). I like this better. The harmonica has a more yearning quality, the vocal more forlorn.
