This is the
New Mickey Mouse Club.
It's second in a series of four American versions of The Mickey Mouse Club. (Two more versions aired in Asia.)

A nationwide search was held to find twelve talented kids ages 9-14. The show was billed as a young variety hour with skits, cartoons, songs, and dance. 

Fans know it as NMMC, and they are still awaiting the show's release from Vault Disney. It has not been aired since the 70's, with the exception of 10 episodes on The Disney Channel in the network's early days. Some wobbly VHS has survived from fans and has been uploaded, But for the most part, this cast is lovingly referred to as The Forgotten Mice. We hope that changes!
