Where these chords come from: an expert transcription of the original recording made for the McGill Billboard Project (Burgoyne, Wild & Fujinaga, 2011).

Consecutive repeats of a chord are shown once, and the piano voicings are our playable arrangement of each chord symbol, not a note-for-note transcription.
