Haha! No, seriously, I can go on and on forever just discussing these two chords. From the musical point of view I can explain almost everything and say exactly why this note or chord was chosen, and that's the reason for the fast transcribing process. I love when music is not subjective, but objective thing. Mark's music (and especially riffs) often contain certain parts that give the overall sound of the song, and together with complex right hand playing this is that people would call his 'style'.
Although this all been said, the very last chord of the song, in the very ending HAVE third in it, it was played by Guy on his organ.
This is almost baroque-style ending, see 'And I Love Her' for example. So these little things like this just blows my mind.
