From the Obama fundraiser at the Masonic Auditorium in San Francisco, CA, February 16, 2012. I found the different angles here on YouTube and pieced them together. Many thanks to the YouTuber's whose videos I used; including... concertkid2 (audio also), julissa321, srscanlan, matthewalb, yar1960, theShivaTV, and rishirich5.
