Opera singer Beverly Sills was honored Sunday by family, friends and fans in a spoken and musical tribute at the Metropolitan Opera House.

“A Tribute to Beverly Sills” was presented by Lincoln Center for the Performing Arts, the Metropolitan Opera and the New York City Opera, according to the Associated Press.

Beverly Sills, who passed away of lung cancer on July 2 at age 78, was remembered as a charismatic and incredible soprano as well as a dedicated fundraiser for various causes.

Barbara Walters said Sills had been her “best friend” while Carol Burnett fondly remembered her as “a brilliant comedian.”

“She had the timing of Jack Benny. She was just fabulous,” Burnett said, referring to a 1976 CBS special she did with Sills. A clip from the material was shown.

Mayor Michael Bloomberg called Sills “a great woman and a great friend” while Peter Gelb, general manager of the Metropolitan, called the soprano “one of the most beloved figures in the history of opera.”

Soprano Anna Netrebko and tenor Placido Domingo both performed.

Sills, born Belle Miriam Silverman, was known by the nickname Bubbles, an endearment that went well with her vivaciousness and generous smiles.

She made her operatic stage debut in 1947, with the Philadelphia Civic Opera, in a small role in Bizet's “Carmen.” She gained wide critical appreciation in 1955, when she first appeared with the New York City Opera as Rosalinde in Johann Strauss II's “Die Fledermaus.”

She was one of the best known American opera singers throughout the 1960s and 1970s and performed at famed opera houses such as Milan's La Scala and the Royal Opera in London.

In 1980, at age 51, she retired from the stage and turned her attention and energy to managing the New York City Opera. She became chairwoman of the Lincoln Center for the Performing Arts in 1994. From 2002 to 2005, she was chairwoman of the Metropolitan Opera.

Throughout her career, Sills frequently appeared on “The Tonight Show,” “The Muppet Show” and in televised performances with her friend Carol Burnett.

She also devoted her time and energy to various causes, both artistic and non-artistic. She supported the Lincoln Center but also as the Memorial Sloan-Kettering Cancer Center, the March of Dimes and the Multiple Sclerosis Society.
