Cover art for Sycamore Leaves lyrics by A-Ha

The lyric is something like Poe's TELL TALE HEART where the narrator murders and buries someone but thinks he hears the dead person's heart beating. Here too seems to be the case: a murderer's conscience torturing him ?

Thinking this lyrics through, quite amazing how dark this and several of the songs on the East of the Sun album are.
