Cover art for Hannah Hunt lyrics by Vampire Weekend

Hannah Hunt was a girl who sat next to Ezra in a Buddhism class in college. She also happens to be a vocalist in the San Francisco indie pop group Dominant Legs. The band had been working on a version of the song since the time of their first album, but it wasn't until now that they felt they got it right

I watched an interview where Ezra was talking about that. I find it amazing that they've worked on this song for seven years until it became a true masterpiece and fit perfectly into this album.
