What on earth is "major phrygian scale in G" supposed to mean? I've always thought this tune was somewhat ambiguous: it could certainly be on a tonal center of G, but to my ear it could also be considered to be on C, ending on the 5th. Either way, it escapes the standard mode categories, with a major 3rd and flat 6th (on G). A salient characteristic of phrygian is a flat 2nd, and this tune doesn't have that.
