Misty Mountain Hop

"Misty Mountain Hop" is a song from Led Zeppelin's untitled fourth album. In the US and Australia it was the B-side of the "Black Dog" single, but still received considerable FM radio airplay.

The lyrics mention an encounter with the police after getting stoned in the park, and leaving to go to the Misty Mountains ("where the spirits fly"), which seems to be a reference to The Hobbit.
