musical theater thought - original casts

If you could go back in time and see any 5 original casts perform in their original productions, what would they be?  It can be a hard question to answer.  Do you see shows for their historical significance? or their songs? or their star turn? or their groundbreaking choreography? Or design elements?  Or a combination?  There are so many things to factor in when one travels in a Broadway time machine.  After much pondering, here are my five:

1.Follies was another groundbreaking Sondheim musical that followed up another groundbreaker, Company.  These kinds of concept musicals had never really been seen on the great white way before.  With an original cast full of old Hollywood with Alexis Smith, Gene Nelson and Yvonne De Carlo, the stunning and haunting score by Sondheim, and a production design that has never been equaled because it would be too expensive today.  This one is a must see!

2.Camelot is a score that i have loved as long a i can remember.  Even though this show definitely has some book problems, i find the music beguiling and filled with emotion.  But, for me, it is the cast that would draw me to see this one.  i mean, really.  Julie Andrews, Richard Burton, Robert Goulet and Roddy McDowall on the same stage?  yes please!

3.Mame is another show where the original cast is the draw for me.  As a huge fan of Angela Lansbury and Bea Arthur, how could i resist them on stage together singing "Bosom Buddies".  And Jane Connell, one of the best character actresses in musicals in the golden age of Broadway.  Even though the show was not the critical success Jerry Herman had with Hello, Dolly!  and La Cage Aux Folles, this score is my favorite of his!

4.A Chorus Line.  How could i not go back and see this one.  An original concept musical about dancers singing about their lives.  And they literally were.  The stories were drawn from the lives of dancers, many of whom were in the original cast.  Amazing choreography and direction by Michael Bennett, and a score by Marvin Hamlisch and Edward Kleban.  Pulitzer Prize winner.  Doesn't get much better.

5.Gypsy was the pinnacle of Ethel Merman's career.  If she hadn't already been deemed legendary, this star turn totally secured that.  A tour de force written for her, the score by Jule Styne and Stephen Sondheim is one of the most perfectly constructed ones ever written for the theater.  To see her in the role of a lifetime would be amazing!

So there's my list :)  What would you travel back in time to see?  Of course, it's hard to choose and there are lots of honorable mentions:
Dreamgirls, A Little Night Music, Dear World, Evita, Applause, Once On This Island, etc.  I know there are many more :)

Cheers!
