On March 19, 1977, CBS aired the series finale of the critically acclaimed Mary Tyler Moore Show, "The Last Show". In it, a new station manager (Vincent Gardenia) takes over WJM-TV and fires Lou Grant (Ed Asner), Mary Richards (Moore), Murray Slaughter (Gavin MacLeod), and Sue Ann Nivens (Betty White) - but keeps Ted Baxter (Ted Knight). With Mary under distress, Lou arranges for two of her old friends, Rhoda Morgenstern (Valerie Harper) and Phyllis Lindstrom (Cloris Leachman), to fly in to Minneapolis for a surprise visit to the apartment. Later, following the news team's final broadcast together, they gather in the newsroom to say goodbye. (Lou would eventually be hired by the Los Angeles Tribune in the more dramatic spinoff series, Lou Grant, which ran five seasons from 1977 to 1982.) Since its broadcast, this finale has been ranked among the greatest of all time.

But on its original broadcast, just before the closing credits, a final curtain call appeared. Here, Moore introduces "the best cast ever" by name before they take their final bow. This was cut from syndicated airings, and for years fans have tracked down this final curtain call. However, in 2010, 20th Century Fox Home Entertainment included it on the DVD release of the seventh season.
