WHAT: The Signature Theater Company’s tribute to dramatist Horton Foote on the eve of his 90th birthday.

WHERE: The Ritz-Carlton New York, Battery Park, on Monday night.

FOOTE FETISH: Before a slew of guests including Robert Duvall, Matthew Broderick and Peter Sarsgaard paid homage to Foote, Dame Edna (Barry Humphries) took the stage to read a poem in the scribe’s tribute.

“I will make this very brief,” Dame Edna said before joking, “I have another engagement. My helicopter is being refueled on the roof.”

Later, Sarsgaard recalled his first play, Foote’s Off Broadway “Laura Dennis.” “Boy, do I have a bone to pick with you, Horton,” thesp said. “You got me into this business, and it ain’t that easy. I learned more in doing ‘Dennis’ than I have learned in so many things since. Horton is an actor, so he always gives you the chance to choose your own adventure, and that’s what I learned. I learned later on that nobody else gives you that chance. It was a painful (discovery).”
