A deathless nylon-string favourite, even though it has no catchy chorus. The melody over that 12-bar chord progression is simply great songwriting. This arrangement is simplified a little to be able to play melody and accompaniment at the same time. From the 1982 „Love Over Gold“ album, which some call a „prog-rock effort“. Rubbish. It is just that the songs are a little longer.
This is only the beautiful intro. Played very slowly, with lots of slides, hammer-ons and pull-offs. Keep the chord arpeggios in the background of the melody.
