Dancin' On Air was a 1980s television dance music reality show, forerunner of the TV show "Dance Party USA".  Both shows were produced and created by Michael Nise and his father Frank.  The show started with US$100,000 from a small group of investors that included "The Tonight Show Band" leader Doc Severinsen.  The program earned a 128% return on investment (ROI) within the first six months.  "Dancin' On Air" was produced at WPHL Channel 17 studios in Philadelphia Pa. Carl Hilding "Doc" Severinsen (born July 7, 1927) is an American pop and jazz trumpeter.  He is best known for leading the NBC Orchestra on "The Tonight Show Starring Johnny Carson". 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 an ironic take on his low-keyed, often dour persona, he was often a foil for Johnny Carson's humor.  His brown or blue suits were a marked contrast to Severinsen's flashy stage clothing. Blaire Reinhard is a singer, pianist, and songwriter from Morristown, New Jersey.  She is the granddaughter of trumpet player and Tonight Show bandleader Doc Severinsen.  On September 7, 2012, her single "No Nothing" with Curtis & Reinhard reached #92 on the iTunes US Pop Music Chart. Frank Proto is an American composer and bassist.
