  Season 2   (1956-57)  

  Fun With a Camera #1  
  Oct 3, 1956  
  Lead: Earl Theisen  
  With: Eileen, Sherry, Kevin Corcoran, Jack Jackman  
  This was a five-part series in which photographer Earl Theisen from Look magazine taught the kids how to use a camera. They visited several locations, including the San Diego Zoo and Disneyland. Jack Jackman was not a Mouseketeer, but was used for two ACH series. He was likely the son of Bob Jackman, then head of the Disney Music Department.

  Fun With a Camera #2  
  Oct 10, 1956  
  Lead: Earl Theisen  
  With: Eileen, Sherry, Kevin Corcoran, Jack Jackman  
  This series was shot on film without sound. Voiceover narration by Eileen and sound effects were added later in the studio, as was commentary by Earl Theisen. There were no titles, theme song, or credits. It was just a barebones newsreel style feature that was inexpensive and quick to make.

  Rookie Fireman #1  
  Oct 17, 1956  
  Lead: Walt Disney, LAFD Personnel  
  With: Eileen, Sherry, Charley, Jack Jackman  
  Another educational series, this followed the four kids as they trained to be rookie firemen. Walt Disney himself hosted this series. Portions may have been filmed at the Disneyland Firehouse; other portions were likely done at Los Angeles Fire Department training facilities. Because of the physical exertions required, the kids were allowed to wear jeans instead of slacks and skirts.

  Fun With a Camera #3  
  Oct 24, 1956  
  Lead: Earl Theisen  
  With: Eileen, Sherry, Kevin Corcoran, Jack Jackman

  Rookie Fireman #2  
  Oct 31, 1956  
  Lead: Walt Disney, LAFD Personnel  
  With: Eileen, Sherry, Charley, Jack Jackman  
  This was filmed after the Fun with a Camera serial. Kevin Corcoran, who appeared in the latter, was promoted to the major serials. Unable to find another small boy to match up with Sherry, the producers instead drafted Charley Laney. Charley was ragarded as the best looking boy on the show, was quite popular with the Mouseketeer girls, but wasn't considered much of a dancer by director Sid Miller.

  Cubby was the one of the most popular Mouseketeers in the amount of fan mail received, and like Annette had been personally selected by Walt Disney.
