Fleetwood Mac - harmony?

It's ironic to apply the word "harmony" to the mid-1970s/early-1980s version of Fleetwood Mac (see my previous post on the various versions of the band), since their personal relationships were anything but harmonic. But despite everything, Christine, Stevie, and Lindsey still managed to come up with the best vocal harmonies this side of the Beach Boys.

Take a listen to Little Lies.
