Watch this live version of "Black Dog" performed by Led Zeppelin, the greatest rock band of all time! The song's title is a reference to a nameless black labrador retriever that wandered around the Headley Grange studios during recording. https://www.facebook.com/sharer/sharer.php?u=http://youtu.be/6tlSx0jkuLM http://www.ledzeppelin.com/ http://www.facebook.com/ledzeppelin https://twitter.com/ledzeppelin http://www.youtube.com/ledzeppelin
