The Pious Bird of Good Omen

[sharksfan2000]

Doesn't seem like any mystery, does it? The albatross on the cover speaks for itself, and of course it ties into the name of the album. And if you know stories about early Fleetwood Mac (perhaps you don't), they were well-known for their attempts to shock their audience with acts and images of questionable taste - the cover of Mr. Wonderful being a case in point...or Google "Harold" in relation to the band - so the pregnant nun on the album cover would be entirely in keeping with that. Don't know that there's anything more to the story than that.
