The astonishing claims about the Birmingham-born Black Sabbath icon, who died last year, were made by American heavy metal star Dee Snider, of Twisted Sister.

In a post on X, he claimed Black Sabbath bassist Geezer Butler penned all of the band's lyrics.

He also claimed Ozzy's first two solo albums featured lyrics written by Bob Daisley, and that the No More Tears album had contributions from Lemmy Kilmister.

Snider also suggested that Sharon Osbourne "doesn't like to share" while discussing the legacy of Ozzy's music, but aded that while many artisits don't write their own material they can still make songs their own.
