My two favorite lines in the song are "If there's a bustle in your hedgerow, don't be alarmed now. It's just a Spring clean for the May queen".
What, exactly, does that mean? That's the part with the (alleged) satanic backmasking, so maybe Page and Plant were pledging allegiance to Aleister Crowley and Anton LeVay through coded messages that were only meaningful when played backwards? Sometime words have two meanings, and sometimes they have no meaning at all. It really makes me wonder.
"Stairway To Heaven" is proof that words don't have to mean anything to be meaningful. I mean, what's this: "If there's a bustle in your hedgerow don't be alarmed now"? If I found anything bustling in my hedgerow I'd get out my shotgun!-- Chuck Eddy
