Thanks for your feedback everyone. I'll certainly check out the other versions of the song.

For example, your use of an E# rather than an F (and your intended use of an F## rather than a G natural) seems to be overcomplicated for the sake of it.

I was trying to be faithful to the key signature, and also have as few accidentals as possible. The run E#, F(sharp), F double sharp, G (sharp) would only need 2 accidentals (the sharps in brackets covered by the key signature). Your suggestion of F natural, F sharp, G natural and G sharp would need 4 accidentals. I'm not sure putting the chord symbols/names helps, because the bass line is just a chromatic run under fairly simple chords in this case. Or am I missing something?
