Led Zeppelin, The Beatles or Black Sabbath - or....

Just Pinned to Black Sabbath: Well the opinions may vary, it is widely believed that the birthplace of rock'n roll was either in Mississippi with Elvis or in London with the Beatles. When it comes to who is the biggest Rock band to ever emerge from United Kingdom, most people would say the Beatles or Led Zeppelin, but what about Black Sabbath from Birmingham England?

I think this heavy metal meme says it all.
