Mark Zuckerberg gave the commencement address at Harvard University's graduation ceremonies on Thursday -and grabbed most of the headlines. But he wasn't the only celebrity on hand. Ten honorary degrees were bestowed, including a doctor of music to composer John Williams. The Harvard Din and Tonics, an a cappella group, performed a tribute to Williams during the ceremonies.
The medley of movie themes included music from Star Wars, Raiders of the Lost Ark, E.T.: The Extraterrestrial, Superman, Jaws, and more. (via Laughing Squid)
