LOS ANGELES (AP) — It turns out "The Last Show" wasn't the last, after all.

Actress Mary Tyler Moore and some of her former colleagues gathered Thursday afternoon for a news conference at CBS Studio Center to discuss their first sitcom appearance together since "The Last Show," the title of the 1977 series finale of the groundbreaking "Mary Tyler Moore Show."

Moore, Cloris Leachman, Betty White, Georgia Engel and the ailing Valerie Harper reunited this week to tape an episode of White's hit TV Land comedy, "Hot in Cleveland."

The 73-year-old Harper was especially grateful for the reunion after her recent diagnosis with terminal brain cancer.

She says the reunion with her old co-stars has brought a lot more laughter than tears.
