In a new clip from the guitarist's Scott Ian Swearing Words Live in Glasgow DVD, he says he could barely control himself the first time be met Black Sabbath guitarist Tony Iommi - and so he understands fans who lose their mind when they meet him.

He says: "The one I get all the time is when someone runs up to me and screams either my name or the name of the band in my face as loud as they can. I actually love this because I completely understand the emotion.

"I f***ing get it, because the first time I was in a room with Tony Iommi, all I could f***ing think of was screaming 'Tony Iommi.' I was losing my f***ing mind. I wanted to grab him by his long leather awesome coat. My f***ing brain was gonna explode. That's why I'm saying I get it, and when someone comes up and does that to me I f***ing understand."
