Songfacts®:

• A track on Black Sabbath's conveniently named fourth album, Vol. 4, this one is popular with several famous musicians: Beck and Frank Zappa have both mentioned "Supernaut" for its awesome guitar riff written by Tony Iommi.
• Ozzy Osbourne was Black Sabbath's vocalist at this time, but their lyricist was their bass player, Geezer Butler. On "Supernaut," the theme is escapism, with a touch of fantasy. The character in the song been through magic and lived a thousand years.
• The title doesn't show up in the lyric, and the song doesn't have a chorus - it doesn't need one with Tony Iommi's guitar riff clearing the path.
• In a Songfacts interview with Tony Iommi, he talked about writing this song. "I had a wah-wah going and started playing this riff, which was 'Supernaut,'" he said. "Everybody liked it, and we made it into the song."
  
  "That's how we always went about the Sabbath stuff," he added. "I always played something and the others would have to go, 'Oh, I like that.' If nobody said anything about it, we'd just carry on and do something else. It always had to be somebody going, 'Oh, I really like that,' because I can keep playing riffs."
• Sometime (no one knows when) and someplace (nobody knows where), this song became seed for one of rock's great unrecorded, mythical events - a Black Sabbath/Led Zeppelin jam session. Memories conflict as to the details, but all agree that the jam happened. Sabbath drummer Bill Ward recalls that it came together because Zeppelin drummer John Bonham loved "Supernaut," so the groups met while Sabbath were in studio working on an album (no one can recall which album) and jammed on it. Nothing was recorded, no notes were taken, but the moment lives on in the realm of rock and roll legend.
