Sing Along with Mitch, airing on NBC from 1961 to 1964, was a weekly sing-along program hosted by Mitch Miller and featuring a male chorus. Lyrics were presented at the bottom of the television screen. Singer Leslie Uggams, pianist Dick Hyman, and the singing Quinto Sisters were regularly featured. 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. As the popularity of the show rose, Miller produced and recorded several "Sing Along with Mitch" record albums.
Name That Tune is an American television game show that put two contestants against each other to test their knowledge of songs. Premiering in the United States on NBC Radio in 1952, the show was created and produced by Harry Salter and his wife Roberta.
Name That Tune ran from 1953–1959 on NBC and CBS in prime time. The first hosts were Red Benson and later Bill Cullen, but George DeWitt became most identified with the show.
Richard Hayes also emceed a local edition from 1970–1971, which ran for 26 weeks in a small number of markets. However, the best-remembered syndicated Name That Tune aired once a week from 1974–1981 with host Tom Kennedy. The series was revived for daily syndication in 1984, and its lone season was hosted by Jim Lange. For the last two of these series, John Harlan served as announcer.
The centerpiece of each Name That Tune series was an orchestra, which would play the songs for the contestants to guess. The syndicated series' orchestras were conducted by Bob Alberti, Tommy Oliver, and Stan Worth. A second band, Dan Sawyer and the Sound System, was also featured from 1978–1981. Beginning in 1976 and continuing for the remainder of the weekly syndicated series, as well as for the entire 1984 run, the show's title became The $100,000 Name That Tune.
