Al Green will perform at an Obama fundraiser tonight in San Francisco, a month after the president sang “Let’s Stay Together” at an event in New York.

Sales of Green’s song shot up after the president’s performance.

The event, which is not open to the public, will be held at the home of novelist Robert Mailer Anderson, according to ABC News.
