The Killers will close out Outside Lands tonight in San Francisco, and they showed up a day early to play a relatively intimate gig at the Independent. Haim played Outside Lands yesterday, and since they are buddies with pretty much everybody in the music industry except Johnny Marr and Los Campesinos!, they were of course at the venue to party with the Killers. During the encore, Brandon Flowers sung Haim’s praises and invited Danielle Haim on stage to play drums during a rare run through “On Top.” Watch fan-made video below.
