"Somewhere"

I've always been impressed by Tom Waits' heart-rending version of "Somewhere" from "West Side Story". It's an amazing thing, but it's all lush orchestra chords -- impossible to decipher. But, I found a MIDI file, and analyzed the bass line, and worked out the chords -- not too hard after all. Amazing writing: there's at least one of every "letter" in there; D, E, F, F#m, G, A, Bb, Bm, and C. It's in D, I guess. Not sure I'll try to do it in public, but it's nice to have finally cracked it.
