Ozzy's Granddaughters Singing Crazy Train Will Bite The Head Off Your Heart

Though all metal fans feel like Ozzy Osbourne is their grandpa, the Prince Of Darkness also has actual grandkids via his son Jack. And it looks like Pearl and Andy, Jack's two eldest, are carrying on Pop Pop's tradition of belting out heavy metal tracks to the world, as indicated by this heartwarming video Jack posted on Instagram.

Watch Peal and Andy sing Ozzy's classic Crazy Train and erupt into an impromptu heavy metal dance party:

Sharon Osbourne later shared the video on her show The Talk, beaming at her granddaughters as the studio audience cooed in unison.

"Do you see the way Andy sneaks in, and then she starts the headbanging?" laughs Sharon. "They did that to make their Papa feel better!"

Sharon is of course referring to Ozzy being hospitalized due to flu complications, which caused the singer to cancel his European tour dates. However, both Jack and Sharon have kept the public consistently updated on Ozzy's condition, and recently said that he's back to his normal routine.

“Well, if this gauges where he’s at, he’s complaining a lot and he’s back to his normal routine. So everything’s A-okay,” said Jack, while Sharon added: “That’s always a good sign, when he complains and he’s miserable then you know it’s good.”

“It’s when he’s happy and skipping around, you’re like, ‘There’s something really wrong here. Call the doctor!’” Jack said.

“Ozzy recently developed pneumonia and has spent some time in hospital,” said Sharon at the time. “He is through the worst part.

All of us at Kerrang! hope Ozzy is doing well, especially with the melted heart we're sure he dealt with upon watching his granddaughters headbanging to his biggest hit.
