The Killers got an assist from Haim frontwoman Danielle Haim during a show in San Francisco this weekend.  But rather than lend her voice to show, the multi-talented musician got behind the drum kit for a performance of the early Killers track "On Top." 

When frontman Brandon Flowers introduced Danielle at the beginning of the band's encore at the Independent, he called Haim a band that gave him "hope for people playing music." 

Both Haim and the Killers were in the City by the Bay this weekend for the Outside Lands festival in Golden Gate Park.
