Mitchell William "Mitch" Miller (July 4, 1911 - July 31, 2010) was an American oboist, conductor, recording producer and recording industry executive. He was involved in almost all aspects of the industry, particularly as a conductor, and artist and repertoire (A&R) man. Miller was one of the most influential people in American popular music during the 1950s and early 1960s, both as the head of A&R at Columbia Records and as a best-selling recording artist with an NBC television series, Sing Along with Mitch. A graduate of the Eastman School of Music of the University of Rochester in the early 1930s, Miller began his musical career as an accomplished player of the oboe and English horn, making numerous highly regarded classical and popular recordings, but he is best remembered as a choral conductor on television and as a recordings executive.

In the early 1960s, Miller hosted the NBC television show Sing Along with Mitch, a community-sing program featuring him and a male chorus: an extension of his series of Columbia record albums of the same name. In keeping with the show's title, viewers were presented with lyrics at the bottom of the television screen, and while many insist there was a bouncing ball to keep time, Miller correctly said this was something they remember from movie theater Screen Songs and Song Cartunes sing-along cartoons.  Singer Leslie Uggams, pianist Dick Hyman, and the singing Quinto Sisters were regularly featured on Sing Along with Mitch. One of the singers in Miller's chorale, Bob McGrath, later went on to a long and successful career on the PBS children's show Sesame Street (he was a founding member of the "human" cast in 1969 and became its longest-serving cast member until his enforced retirement in 2016). One of the show's trademarks was the final number, a group sing-along with the regular house chorale, among whom would be an uncredited celebrity not necessarily known for their singing ability, who was dressed like the others. "Hidden" guests in this closing singalong included Johnny Carson, Jerry Lewis, George Burns, Shirley Temple and Milton Berle.  Sing Along with Mitch ran on television from 1961 until the network canceled it in 1964, a victim of changing musical tastes. Selected repeats aired briefly on NBC during the spring of 1966. The show's primary audience was over the age of 40 and it did not gain the favor of advertisers targeting the youth market. The show's format remained popular in England, where comedian Max Bygraves hosted his own version, Sing Along with Max.  Miller left Columbia Records in 1965 and joined MCA Inc. as a consultant signing the same year with MCA's Decca Records subsidiary.  In later years, Miller would carry on the sing-along tradition, leading crowds in song in personal appearances. For several years, Miller was featured in a popular series of Christmas festivities in New Bedford, Massachusetts, leading large crowds singing carols. Miller hosted a 1981 TV reunion of the Sing Along Gang for NBC (featuring veterans from the original gang, including Bob McGrath, Andy Love, Paul Friesen, Victor Griffin, and Dominic Cortese). Miller also appeared as host of two PBS television specials, "Keep America Singing" (1994) and "Voices In Harmony" (1996), featuring champion quartets and choruses of SPEBSQSA and Sweet Adelines International. He also appeared conducting regional orchestras and filled-in many times as guest conductor of the Boston Pops Orchestra.
