“He’d got it down to a tee. He wore one of my jackets, a wig, a mustache and I’m playing behind him”: Tony Iommi once dressed his guitar tech up as himself and sent him onstage as a prank on Sabbath singer Tony Martin

In a recent interview posted to Tony Iommi's YouTube account, Iommi and Tony Martin have discussed the pranks they played on each other while on tour with Black Sabbath. They mention a particular prank, which included Iommi dressing up one of his guitar techs as him and sending the fake Iommi out on stage.

“They must have planned it for weeks. I was not expecting that, ’cos I'm being all serious, like I said 'Mr. Tony Iommi' and then walks Andy [on stage],” said Martin.
