John Lloyd Walters: I love all the aforementioned performances yet truly admire her walk-on "cameos" on shows like "Late Night" with David Letterman where her "character" thought he was the "Pool Boy" or a little remembered show called "Tattingers" where she stole the scene off-camera singing in the shower. Simply brilliant!

Tom Villella: Loved her as Joanne, but does anyone remember her as a crusty lawyer in early 1990s episodes of "Law and Order"? She was amazing!

Christine Stone: She did an episode of "The Cosby Show." Rudy & Bud's teacher & dance instructor. I just remembered that episode!

Mike Canestraro: Her "To Keep My Love Alive" on PBS "Musical Comedy Tonight III" was priceless. Many ladies have sung that classic, but no one tops Stritchy!

Ira Ratner: I read that she was the first person to play "The Honeymooners'" Trixie when it first appeared as a segment on Gleason's Calvacade of Stars.

Stritch has appeared on numerous hit TV series, including "The Cosby Show," "Law and Order" and "30 Rock." She was also a star on London television.

Tyler Hayes: When I got to see her in the revival of A Little Night Music a show and night I'll never forget. Elaine is a legend!

Stritch replaced Angela Lansbury in 2010 in the Tony Award-winning revival of A Little Night Music. 

Here are some highlights from her performance.

Jean Lohrius: A Delicate Balance.

Michael Giorgio: I'll also say A Delicate Balance... She's known as a brassy musical comedy lady... But this showed she had serious chops as an actor... She shared the stage with Rosemary Harris and George Grizzard and just became both a focal point and a wonderful ensemble member... It was funny, extremely sad, raw, and essentially all of the elements that had her extend beyond an entertainer, but an artist...

Max Daniels: A Delicate Balance was amazing.

Stritch was nominated for a Tony Award for Best Actress in a Play for her performance in the revival of Edward Albee's A Delicate Balance.

Alex Ciesielski: "I'm Still Here" from the Stephen Sondheim Birthday Concert.

Krista Shafer: When she performed at the White House for President Obama. She sang "I'm Still Here" introducing it as a song that really shouldn't be performed by one younger than 80 and then quipped that she had decided to sing it early. She was a great talent.

Daniel Dempsy: "I'm Still Here" but the performance for President Obama and his family at the White House.

Alphonzo Alegrado: Her performance of "I'm Still Here" in "Sondheim! The Birthday Concert." It never fails to put a smile on my face. Especially her passion at the end. Priceless!

Check out this video of Stritch singing "I'm Still Here" at the White House.

Derek J Osgood: I love her in Follies in Concert

David Shipley: "The stage manager said 'Move the bag.' I thought he was talking about me." Follies In Concert ("Broadway Baby")
