For the guitar note I will put it in brackets next to the keyboard note. I
will put the string and fret number.
So  A2 (G14)  means the piano is the A key in section 2 and the note
       for the guitar would be played on the G string on the
14th fret.
Here is the main bass riff played over and over throughout the song.

A--9----------------9-----------------8--------------7----------------|
E-----10---10--10------10--10--10-------10--10--10------10--10--10-10-|
I've organized the song by numbering it, each number represents every time
the main riff is played. Any note under that number shows where and when
Jonny plays the martenot.
