The entire cast of "The Waltons" is to mark the hit show's 40th anniversary by reuniting in Los Angeles.

The surviving stars of the wholesome family series, which ran from 1971 to 1981, will come together at the historic Wilshire Ebell Theatre for a discussion panel, entitled "The Waltons 40th Anniversary: Celebrating Family & Education."

Michael Learned, who starred as Waltons matriarch Olivia, onscreen father Ralph Waite, Richard Thomas, who played eldest son John-Boy, and the show's six other children have all signed up to appear at the fundraiser evening.

Learned tells TVGuide.com, "This reunion, I think, will be the first time that every single one of us will be there... We all loved each other and still do. We were very lucky. I can't think of anybody who isn't grateful for being part of it. We really were a loving family and I think that came through the screen."

Proceeds raised from ticket sales will benefit California's Environmental Charter Middle School, where Kami Cotler, who played the youngest child, Elizabeth, is now principal.
