"A lot of the "Paranoid" album was written around the time of our first album,"Black Sabbath". We recorded the whole thing in about 2 or 3 days, live in the studio. The song "Paranoid" was written as an afterthought. We basically needed a 3 minute filler for the album, and Tony came up with the riff. I quickly did the lyrics, and Ozzy was reading them as he was singing."
