Geezer wrote or cowrote 99% of the songs so not really any revelation

[BernieTaupson]

It’s a total revelation. Geezer didn’t write any riffs during the Ozzy era at all. He did the lyrics. He says in his book constantly that he was frustrated in Sabbath that no one listened to his song ideas. Tony said in his book that Geezer really didn’t contribute to the music until the Cross Purposes album.
