Bassist and metal progenitor Geezer Butler has written countless iconic tracks with Black Sabbath, but one misguided effort from 1976 stands out as "cringy".

According to Metal Hammer, the livestream cut off as Butler and guitarist Tony Iommi went over to Osbourne’s throne to speak to him and shake hands. Butler presented Osbourne a cake decorated with his image as the crowd roared.

Black Sabbath reunited for the first time in 20 years at their farewell show, Back to the Beginning, on July 5, but it wasn't without some drama.
