According to Greg Hernandez's 9/14/06 article in the LA DAILY NEWS:
A boxed set of the not-as-widely-seen 13 one-hour episodes of "Lucy" will be released in early 2007. The show ran in a weekly half-hour format from 1951 to 1957, then switched to monthly one-hour shows for the next three seasons.
The one-hour shows were originally titled "The Lucille Ball-Desi Arnaz Show" on CBS, then syndicated as "The Lucy-Desi Comedy Hour" and "We Love Lucy." Each show featured the original cast, with guest stars such as Milton Berle, Danny Thomas and Tallulah Bankhead.
"People have been asking about the `Lucy-Desi Comedy Hour' a lot" said Gord Lacy, editor of the Web site TVShowsOnDVD.com, where fans vote for which shows they want most to see released on DVD. "The `I Love Lucy' seasons have been released at a steady pace and people are happy with the sets and want more."
The episodes will be released as seasons 7, 8 and 9, but in a single DVD package. They will have some rare gems, including color home movies secretly taken by an audience member during the show's first season. It is the only color film of the Ricardos in their apartment, according to Oppenheimer, who is producing the set.
Also included will be three episodes linked together by 12 minutes of never-before-seen footage that was originally put together as an "I Love Lucy" feature film. But it was shelved and seemingly lost forever until it was discovered recently in an incorrectly labeled film cannister.
