The five-time Tony Award winner, Lansbury told the audience that even though she sang "Bosom Buddies" in Mame with Arthur in 1966, it wasn't until the '70s that they became "Bosom Friends."
"Knowing Bea, she wouldn't have approved," Lansbury, dressed in an elegant off-white pantsuit, said about the memorial.
But Billy Goldenberg, Athur's long-time accompanist said, "This is not a memorial; it's a celebration of our delicious time with Bea."
That celebration, open to the public on a first-come, first-serve basis, began outside the Majestic Theater where a lined of Bea-addicts wrapped around 44th street. Celebrity writer and invited guest, Michael Musto, told Out how he thinks Arthur would like to be etched in history.
"I think she'd like to be remembered as a smoldering, withering, slow burn in a caftan," Musto said.
Drag performer and writer Charles Busch arrived with actress Julie Halston and acknowledged Arthur's influence on the drag community.
"She was one of the first celebrity supporters of so many drag performers," said Busch. "She came out of the drudges of humanity to see drag."
Born Bernice Frankel on May 13, 1922 in New York City, but raised in Cambridge Md., Arthur began her career in the late '40s in the theater. In 1964 she landed her first Broadway show, Fiddler on the Roof, playing Yente the Matchmaker. But it wasn't until 1971 when Arthur made a guest appearance on All in the Family as Maude Findlay, an outspoken and liberal feminist, that she became a household name.
Norman Lear, creator of All in the Family and its spinoff Maude (1972-1978), written especially for Arthur, got chocked up when talking about his star at the memorial.
"If I made Bea Arthur laugh 100 times a day, I could not even the score of the depth and grace of how that woman made me laugh," said Lear. "She had me laughing in nooks and crannies of my body in places where I didn't even know existed."
Rosie O' Donnell with John McDaniel at the piano honored Arthur by belting out the theme song for Maude. Before leaving the stage in tears, O' Donnell said, "She really taught me and every other woman my age how to be a feminist at a time when that was a dirty word and without her I think there would not be as many funny women on television today."
Perhaps the biggest laugh of the afternoon came from a story Rue McClanahan shared. During Arthur's one-woman Broadway show in 2002, McClanahan and her husband Morrow Wilson attended a party at Sardi's. Wilson approached Arthur and thanked her for inviting him "and my wife Rue McClanahan."
According to McClanahan, Arthur took one of her famous long pauses, looked at Wilson and said, "I love Rue! Betty [White] is a cunt!"
McClanahan also talked about her friend's softer side, which often remained hidden behind the strong, brassy characters she portrayed.
During Maude's first season McClanahan's mother passed away over the Thanksgiving holiday. Not knowing who to turn to, she called Arthur, who told her to come over to her house. Once she got there, Arthur brought her back to the guest bedroom and made up a bed. Thirty-seven years later, McClanahan still remembers lying there with Arthur at her side.
"I felt for the first time in six days a feeling of peace coming over me. My grief dissipated," McClanahan said. "I guess she had that sort of motherly quality, didn't she?"
Nobody knows that better than Arthur's sons, Daniel and Matthew Saks.
"Two years ago, mom gave me this tuxedo for my birthday," Daniel explained about his choice of attire. "She loved the way I looked in it so much that she made me promise to use any excuse to wear it -- that's my excuse."
Though Arthur leaves behind a legacy of laughter, the LGBT community will always thank her for being a friend. In lieu of flowers at the memorial, donations were accepted to the Ali Forney Center, one of Arthur's favorite charities. The Center provides a safe environment to homeless LGBT youth.
Last month Carl Siciliano, executive director of AFC, announced the Center would name a residence in Arthur's name.
"Before Bea became involved with us, we only had two sites and could only shelter 12 kids." said Siciliano. "We were struggling to respond to an epidemic of homelessness that was not very well understood, even in the LGBT community. Bea's support and advocacy really helped raise awareness in our community."
In typical Dorothy Zbornak fashion, Arthur had the last word before the lights came up on a tear-stained audience. In a video montage, which featured the last scene of the final episode of The Golden Girls, her husky, yet delicate voice sang the song "A Chance to Sing" from her Broadway show:
We're like birds who are perched on the limbs of a tree When the time is right we simply fly away That other birds come and take our places But they won't stay. We come and go. It was always so. And so it will always be. Before the time when we must fly away We have the chance to sing ...
