John Williams is not the first famous movie composer to do a news theme for NBC. This funky theme, used during the latter period of the John Chancellor era of Nightly News, is composed by Henry Mancini. He has done incredibly recognizable themes such as The Pink Panther. Aside from his work for Nightly News, Mancini also composed an election theme for NBC and the NBC Mystery Movie theme. While his election theme would stay on for decades, his theme for Nightly News only lasted for a short time.
