hehe...
true, that.
you know, i can see that these guys were obviously influenced, and loved that style of music.
i can imagine that they thought, as far as they knew, almost nobody had ever even heard any of that style of music, out in the big ole world outside of the cotton belt, and they were paying homage to it.
as a straight up infringement, i don't think that was strictly intentional, but i do think the ruling was fair.
point is, nobody ever made that kind of music sound that way, before zep, and they've been emulated for it ever since.
kinda cool, as far as rock history goes..
