Megadeth frontman Dave Mustaine spoke in an interview with Jamey Jasta and revealed interesting story between him and Metallica manager Peter Mensch. He said (transcriped by Ultimate-Guitar):

“When I did the Big 4 concert at the Yankee Staduim, I had my neck in a neck brace riding on a golf cart to the stage. I had the tape all over the stage that said ‘Don’t headbang.’

I would have died if I headbanged that night because I was in an emergency surgery room two days before, ready to have my neck operated on.

And I called up my manager at the time, Mark Adelman, and I said, ‘Look, I played with Metallica, Anthrax, and Slayer before, I’ve played New York before, I’ve played a baseball stadium before, so none of this is new to me and I have to cancel because I need emergency surgery.’


So, allegedly, Adelman tells this to Metallica’s management, whatever the guy with the name of a penis, whatever his name is… it was Dick or Peter or something… Peter!

So he said I was a pussy. So I went, ‘Okay, wrap me up, I’m going to New York.’ They gave me a bunch of injections in my neck and put me in a neck brace and I flew out and played the concert and I came back. Who’s the real pussy now?
