Watch Haim, Grizzly Bear's Ed Droste do 'Surfer Girl' at starry benefit

The sold-out show at the Troubadour featured Kesha, Guster, Jenny Lewis, and more

Today in gutwrenching FOMO: the Haim sisters hosted a star-studded, sold-out benefit show at the Troubadour in West Hollywood last night. As one might expect from a band who kicks it regularly with Taylor Swift, the night was jam-packed with guest performances, including Grizzly Bear frontman Ed Droste, with whom the band played a cover of the Beach Boys' "Surfer Girl."

The night also featured support from Grizzly Bear's Rostam Batmanglij, Kesha, Guster, Jenny Lewis, Laura Marling, and the girls' own former bandmates: their parents Moti and Donna. Known together as Rockinhaim, the family covered "Johnny B. Goode" and "Mustang Sally." (And of course, no celebfest would be complete without an appearance from T-Swift herself, accompanied by reported new beau Calvin Harris.)

Called "Sam Jam" and billed as "Haim and Friends," the show was organized in memory of the sisters' friend Sammi Kraft, who died in a car accident in 2012. Proceeds were donated to Our House Grief Support Center, a local organization that offers grief counseling and resources for families.

Watch the "Surfer Girl" clip above. Lewis also premiered a new song, "Girl on Girl," during her segment, You can hear that here. (Unless you're a country radio exec.)
