This main riff is almost verbatim from a sabbath song or the like, can one of you tell me which one?
nah man, I aint gonna fish through your questionable song choices looking for a Sabbath riff, errybody rips off Sabbath.
Its the main riff, it starts 38 seconds in
I think it may be Hole in the Sky. Sort of sound like it
truly madly deeply 1:55
They stole from OZzy.
I agree with ZeppelinSkynyrd, it's got the same vibe as "Hole in the Sky".
