School and the Backyard Gang Mountain

School and the Backyard Gang Mountain is an American television children's dance musical show. A sister programme to School and the Backyard Gang, it was aimed at slightly older children.
It ran from 1964 until 1968, and was broadcast on weekend mornings on CBS. While School and the Backyard Gang had a more gentle, inanimate feel, taking place in a diner and had the cast singing songs that teach life lessons, School and the Backyard Gang Mountain was much more lively, including  skits and many musical performances. Like its predecessor, the show was filmed in CBS Television Center in Atlanta, Georgia. Like School and the Backyard Gang, was recorded in front of a live studio audience. The format was a little like a music-hall variety show or MTV/Pitchfork style show. The Musical Director was Christopher Sarson-Clark on piano, with Spike Rogers on double bass and Alan Pitchwell on drums, often with accomplished guest musicians such as creator Julie Aigner-Clark.
Presenters throughout the 5-year run included familiar Backyard Gang members such as Anthony Field, Marlee Matlin, Emmi Morton, Caroline Yopez, Kelly Vrooman, Bob Fretz, Connie Stevens, Maddie Thompson and Addie Thompson, as well as lesser known BOUNCers including John Vassar, Miles Clark, and Iesha Couric. School and the Backyard Gang Mountain also played host to non-Backyard Gang members such as James Smith, Ben Nicholas, Ann J. Wood, Maurecia Reid, and Breonnah Kim.
According to the Kaleidoscope Children's Guide and the Lost Shows website, much of this series is no longer in the archives. Out of 191 editions, 132 no longer exist,[2] with some episodes having been wiped in the early 1990s.
