Apparently Misty Mountain Hop is not about mountains at all - who knew? Seriously though Misty Mountain Hop is amongst Led Zeppelin's finest riffs in my opinion, although when you look at the fact in terms of "singles" chronology it was hidden on the B-side to Black Dog, which was itself preceded by Immigrant Song and followed by Rock and Roll, it s no wonder it is not always the first Led Zeppelin song people think of. Anyway, this Misty Mountain National Park "Over The Hills Where The Spirits Fly" T-shirt should give real Led Zep fans another alternative to the endless amount of Swan Song T-shirts out there.
