(MASON )-Three actors from ``The Brady Bunch'' television series were at Kings Island Sunday afternoon.

Actors Barry Williams who played Greg Brady, Christopher Knight who played Peter Brady and Susan Olsen who played Cindy Brady were there to celebrate the 40th anniversary of a popular episode of their 1970s TV show.

The episode called ``The Cincinnati Kids'' aired in 1973 and was filmed at Kings Island. It involved the family visiting Kings Island so dad Mike Brady played by Robert Reed could present his architectural plans for a new addition to the park.

The three actors met fans and signed autographs during four shows of singing, dancing and anecdotes from the show that ran from 1969 to 1974.
