To me, they're hardly Led Zeppelin. A laughable comparison, really.
In fact, I would say that they want you to think Led Zeppelin when you hear them, so you'll be that much less likely to realize the song posted by the OP is a shameless rip-off of Nazareth's "Hair of the Dog" (Now you're messin with a son of a bitch).
