She is extraordinary. She dances with every INCH of her body! The gesture and the tension. Blowing me totally away.

This is historic. One of the greatest numbers in musical theatre.

No one danced this like Donna... and no one ever will!

People just don't SING like this anymore. Of course it was before the days of body mics and all they had were mics on the foot of the stage. But still, despite hearing any imperfections in this raw performance, what you DO HEAR is the spirit of a charactor singing for it's very life!

No other actress will ever come close to Donna. She owned the role of Cassie.

This is a wild and mysterious bootleg video. It's great to see it!! Donna McKechnie is awesome.

The greatest dance number in American musical theatre.i saw her twice downtown and the Schubert

Only cassie that was a born dancer and not just an actress that could dance.

I'm amazing by how flexible she was, especially her back bend at 7:55.

When I was in high school (1978-82) we usually did not use mikes and had to speak and sing out. It wasn't a huge auditorium, 1500 seats including a balcony, but I remember the drama teacher always yelling "Project!!" ....

One of the greatest examples of a "triple threat" in Broadway history. Why can't they all be like this?

I've seen this choreography on other bodies. NO ONE does it like Donna. The elegance. The fluidity. Just visual perfection. She moves like a gazelle. No wonder she was Bennett's muse.

Incredible!! Is this from the Off-Broadway "tryouts" at the Public Theatre?? This is truly historic footage. I saw Donna dance this on Broadway with the original cast in July of 1975--the performance and the audience response was indescribable! And to see this now--magic--chills! Thank you for this! :)

WOW!!!! Awesome and never gets old!!! No one does it like her...

They don’t come much better. I saw Ann Reinking as Cassie in 1976 and I thought she was so good it was scary. I can’t believe they used footlights in this show it’s a miracle nobody kicked one and broke a toe

She's magnificent!!!!

Goosebumps watching just like I had them when I saw the OBC back on my first ever trip to NYC! Total magic.

this is amazing! its crazy to be able to see a piece of broadway history that would otherwise have completely unnoticed, THANK YOU FOR POSTING!!!

Dance ... 10 !!!!!!

I saw her; I was 13!!!

She was brilliant in this show.

Is there a better musical theatre dancer than Donna McKechnie? I doubt it.

Bravo! Again and again...

Wow! BRAVO, Donna.

Spectacular!!!

Iconic

They don’t call this showstopping for nuthin’

Oh my god❤❤❤❤❤❤

She's so Broadway and whatever she wants. Wish she could see my kids.

Opening night 1976 get it Barbara

I’m sorry but Michael’s original choreography in this drove me nuts. Kinda all over the place with frozen weird ballet arm positions. Halting and quite disruptive. However, and what made him an incredible Director is He played to the strengths of the incredible Donna! This is no dish to her, but her musicality, extensions and expressive feet were what stole this song! Technique? Hmmm. Todays Cassie’s do DOUBLE pirouettes repeatedly down the chorus “line”. Donna, not so much, she fudges it with footwork and a lot of shuffling. Her voice is SPECTACULAR! I do love that Michael and Donna created something special for HER and the SHOW. Other Cassie’s may be better technically but not hold up to the well rounded expressionism that is Donna’s lyrical quality.

Donna cast a spell when doing this number. Other try, but theyre basically cheerleaders, not artists

They put a man on the moon (?) and had better video than this.
