The Greensleeves point was, as I read it, that the melody partly uses the harmonic minor scale similar to Spanish tunes in the Phrygian mode (where typically Am, G, F and E chords could be used). Runaway does so too, only for the verse and solo, but then so partly do countless early country dance tunes, plus a host of more contemporary songs (One Meat Ball, St. James Infirmary, The House of the Rising Sun, The Cat Came Back, One More Cup of Coffee, Things We Said Today, Lady Darbanville, Portland Town, Babe, I’m Gonna Leave You, Anathea, plus some by Leonard Cohen).
