Thomas Penn "Tommy" Newsom (February 25, 1929 – April 28, 2007) was a saxophone player in the NBC Orchestra on The Tonight Show Starring Johnny Carson, for which he later became assistant director. Newsom was frequently the band's substitute director, whenever Doc Severinsen was away from the show or filling in for announcer Ed McMahon. Nicknamed "Mr. Excitement" as a sarcastic take on his low-keyed, often dour persona, Newsom was often a foil for Carson's humor. His brown or blue suits were a marked contrast to Severinsen's flashy stage clothing.
