Former METALLICA bassist Jason Newsted has revealed that he and MEGADETH mainman Dave Mustaine may perform a classic METALLICA song on the upcoming Gigantour.Newsted, who quit METALLICA in February 2001, is the frontman of a new band, simply called NEWSTED, which was recently this year's edition of Gigantour, the critically acclaimed package festival founded in 2005 by Mustaine. Mustaine, who was one of the original members of METALLICA, was fired from the band by drummer Lars Ulrich in 1983. He was replaced by Kirk Hammett and went on to form MEGADETH and achieve worldwide success on his own. In a recent interview with SkullsNBones.com, Newsted said: "There is a chance that Mustaine and I will bust out some old METALLICA that he was a part of [on the upcoming Gigantour]… There is a chance. It has been talked about. Whatever happens for sure, I don't know [laughs], but I'm willing to throw down 'Phantom Lord'. Actually, whatever he calls out, I'm gonna throw down." Gigantour made its return last year for the first time since 2008. The multi-artist bill — with metal heavyweights MOTÖRHEAD, VOLBEAT and LACUNA COIL all personally picked by Mustaine — kicked off on January 26, 2012 in Camden, New Jersey and wrapped on March 3, 2012 in Austin.
