James Hetfield joined Alice in Chains on stage for a renditon of their song "Would?" Sunday night (November 26) at the Warfield in San Francisco. This is not the first time James has joined Alice in chains. He also did the same song at the Rock am Ring festival in Nürburgring, Germany on June 2, 2006.

According to one Metallica fan who attended last night's alice in chains concert, "Prior to James coming out, they set his guitar up on the side of the stage, but it seemed like no one knew the big secret since only my friend and I saw him arrive (other than crew and friends, I guess, inside). The place went crazy when he came out.
