Key center is Am... look at it from that point of view. It's a minor one chord. Move to C which is the flat III chord. Then the G would be the flat seven chord. The minor scale obviously is the same scale as C major but rather than memorize chord progressions from a minor scale point of view, I like to look at it from the point of view of a major scale with a flat 3 and flat 7 because key centers in many songs change often... and you can't redo roman numerals back and forth in the middle of a song when the key center changes.
So here we have the repeating progression i - bIII - bVII - i. That's sweet. Take it into any key you want that way and it'll work fine.
