You could easily be burnt at the stake for uttering heresies like that.
I'd agree, the Fleetwood Mac version pisses over the Priest version froma great height. Incidently, Fleetwood Mac, a band I'd generally written off, have some stonking tracks I've discovered, can't believe I never really bothered with them.
This reminds me of a debate I've often had with a mate who says that a cover version can never better the original, as the original is the intended version and anything else can never, by definition, be a better version.
