After Dead & Company close their summer tour at the Lockn’ Festival, three sixths of the band will perform at the Centennial Celebration Gala, a benefit for the Save the Redwoods League.

The event – dubbed “The Party of The Century” – will take place on Saturday, October 13 at Union Square in San Francisco. The band is billed as “Bob Weir, Mickey Hart and Friends with special guest John Mayer.”

CBS national correspondent Lee Cowen will be the master of ceremonies, and tickets range from $1,000 to $10,000.

This event will be the band’s second benefit performance in recent memory. In July, the full Dead & Company lineup performed at a Hollywood benefit for Oceana and raised over $1 million for ocean preservation.
