MEGADETH‘s Dave Mustaine joined Metallica onstage the other day to play songs from ‘Kill ‘Em All’ with the band at The Fillmore in San Francisco, in celebration of Metallica’s 30th anniversary. And if that wasn’t enough, the crowd were treated by Geezer Butler and Ozzy Osbourne also popping by to perform ‘Sabbath covers that included ‘Paranoid’, ‘Iron Man’ and ‘Sabbra Cadabra’.

We spotted a picture of Mustaine and Hatfield together, which reminded us of an old skool photo from way back when. Ladies and gents, may we present…
