Metallica is postponing a planned charity concert in San Francisco until later this year.
The band is pushing its All Within My Hands Helping Hands Concert from March 28th to Sept. 12th, telling fans "We may have been a little too ambitious with that date in terms of getting our s*** together" for the show.
Metallica has yet to perform onstage since singer James Hetfield entered rehab last September. They're scheduled to tour South America starting April 15th.
