This song is an instrumental piece with a vocalising choir. The title is a combination of the words superstar and tzar, which is a variant of the word czar, a Russian emperor.

Guitarist Tony Iommi wrote this track at home with a Mellotron to create choir sounds. They ended up booking the London Philharmonic Choir and a harpist. Ozzy wasn’t initially aware of this. He walked in, saw the choir and harp, and immediately walked out thinking that he’d gone to the wrong studio.
