Jesus Was A Cross Maker and The Lamb Ran Away With The Crown are the too that I know and love, the former especially. I didn't really know anything about her life until just now, though.
Famous Blue Raincoat is one of my favourite Leonard Cohen songs. I think he lyrically became more interesting, and more mature (if you can say that about a writer who didn't start releasing records until his mid-30s anyway) as he musically moved into cheap synths and weird production choices that make some of his later music a more acquired taste, but this is right at the point where he's moved beyond the likes of Suzanne/So Long, Marianne, which, while great, always have the feel of a bit of a dirge about them, while simultaneously reminding me of middle class hippies. He feels much more unique as an artist here - when Nina Simone sang Suzanne, it didn't feel like a Leonard Cohen song, whereas anyone who sings Famous Blue Raincoat sounds like they're working in his wheelhouse.
