Which guest star joined the cast for a hilarious take on Sunset Boulevard on the September 29, 1973 episode?

Proving herself a seriously great sport, Swanson had written Burnett to tell her how much she enjoyed the comic's portrayal of aging, has-been screen legend "Nora Desmond" — a take on Swanson's Norma Desmond from Sunset Boulevard. Naturally, the show responded with a guest spot invitation, which Swanson gamely accepted.
