According to fellow Palmer supporter and Hypebot fan Mike Masnick, "one of her fans suggested the morning of the gig that she learn this song by Cat Stevens. So she did. And she went to the beach and a bunch of her fans showed up and she played some music and everyone was happy. And then they realized that the setting was great to film a music video. One of the people there was Danna Kinsky, who hardly knew Amanda, but is a filmmaker, and had her camera. Another person there was Lindsey Barnes, a photographer, who agreed to shoot some photos of the group. And, with the help of (actress) Kirsten Vangsness to corral and organize people, they created an impromptu music video...The whole thing (except editing) was thought up, organized and completed in 20 minutes."
