Just Scott on guitar.
From the youtube video: "various anthrax affiliates played in this song with the lineup consisting of Whitfield Crane- Ugly kid joe, singer, John Marshall- Metallica backup, rhythem, Scott Ian- Anthrax, lead guitar, Tony Levin- Bass guitar, Mickey Dee- Motorhead, drums
All editting done by Anthrax's editing team and owns all credit and copyrights for the song.
sorry for any real confusion but anthrax has official credit for this song but with altered lineup. and for all of you who are mad about me giving the song the anthrax name than give up cause im not going to rename it "Anthrax and Friends". just enjoy the music, i mean anyone affiliated with anthrax are known for their great metallica covers..."
