The present Glenn Miller Orchestra was formed in 1956 and has been touring consistently since, with various leaders, playing an average of 300 live dates a year all around the world.
Singer Nick Hilscher became the director of the touring band in 2012, replacing previous director Gary Tole. http://en.wikipedia.org/wiki/Glenn_Miller_Orchestra

For the original orchestra see Glenn Miller. He was born in Clarinda, Iowa on March 1, 1904, the son of Mattie Lou (née Cavender) and Lewis Elmer Miller.[1][2] He went to grade school in North Platte, Nebraska. In 1915, Miller's family moved to Grant City, Missouri. Around this time, Miller was given his first trombone and then played in the town orchestra. In 1918, the Miller family moved again, this time to Fort Morgan, Colorado where Glenn went to high school. During his senior year, Miller became very interested in a new style of music called "dance band music". Miller enjoyed this music so much that he and some classmates decided to start their own band. By the time Miller graduated from high school in 1921, he had decided he wanted to become a professional musician.[3]

In 1923, Miller entered the University of Colorado where he joined Sigma Nu Fraternity,[4] but spent most of his time away from school, attending auditions and playing any gigs he could get, most notably with Boyd Senter's band in Denver. He dropped out of school after failing three out of five classes one semester, and decided to concentrate on making a career as a professional musician. He later studied the Schillinger technique with Joseph Schillinger,[5] who is credited with helping Miller create the "Miller sound", and under whose tutelage he himself composed what became his signature theme, "Moonlight Serenade."[6]
