Yes, so many.
NORTHWEST PASSAGE, Stan Rogers (among other of Stan's songs)
BLUE, Joni Mitchell
WALKING ON A WIRE, Richard Thompson (and more other songs than I can count by Richard Thompson)
I'M A DREAMER, Sandy Denny (and I wish I could sing it with the same impact as Linda Thompson)
HEART LIKE A WHEEL, Anna McGarrigle
BORN IN CHICAGO, Paul Butterfield (I think, though it may have been a cover)
ONE LIFE TO LIVE, John Mayall
HEROIN, Lou Reed (though I'm glad I couldn't have)
DO NOT GO GENTLE INTO THAT GOOD NIGHT, Dylan Thomas (John Cale has a version, on "Fragments of a Rainy Season", that sparkles)
