and, for curiosity's sake, the first preview of Merrily We Roll Along which apparently had most of the audience walk out before the first act was over.
Funny Girl OBC, Mame OBC, and the JRB Parade OBC. Honorable mentions: Titanic OBC, Ragtime OBC, Follies OBC, Secret Garden OBC, Doctor Zhivago OBC, and N2N with either Jessica Phillips or the gorgeous, late, great, Marin Mazzie.
Since I'm so damned old, and have been going to theatre since the late 1950s (got to see Merman in HAPPY HUNTING, GYPSY, ANNIE GET YOUR GUN and DOLLY), my picks are a bit different (although I love reading the lists):
1. ANYONE CAN WHISTLE with Lee Remick and Angela Lansbury (I had tickets, could only go to Saturday matinees, and the show closed before my May matinee came up, never got over it, and convinced Steve and Arthur to let us do an off-Broadway revival in 1992 as a three-week benefit for BroadwayCares/EquityFightsAIDS).
2. THE MUSIC MAN with Robert Preston and Barbara Cook
3. CAMELOT with Richard Burton and Julie Andrews (saw it near the end of its run, with William Squire, a Welshman like Burton, giving a wonderful carbon copy of Burton, and aging soprano Kathryn Grayson doing unnecessary runs and trills).
I would have loved to have seen the original Show Boat for the historic opening. Second I would have marveled seeing Ethel Merman in Anything Goes and smelled how they perfumed theatres back then. The third ticket would be to see Pal Joey and Gene Kelly dancing.
Fiddler on the Roof (2004 Broadway Revival with Alfred Molina as Tevye) American Idiot (with Billie Joe Armstrong as St. Jimmy) Beautiful (with Melissa Benoist as Carole King)
Honorable Mention: Waitress (with Sara Bareilles as Jenna and Jason Mraz as Dr. Pomatter)
1. Original off-Broadway Assassins 2. Original Streetcar Named Desire (Marlon Brando, Jessica Tandy, Kim Hunter Karl Malden, et al) 3. 2003 Long Day's Journey Into Night (Brian Dennehy, Vanessa Redgrave, Philip Seymour Hoffman, Robert Sean Leonard)
I'd like to see a version of Hedwig and the Angry Inch with John Cameron Mitchell, either the original run or the Broadway revival, I don't mind which.
The other two would be one of the previous versions of Hadestown, to see how it evolved over time, and The King & I with Yul Brynner.
One of the benefits of being an old geezer is that I got to see all the great shows with their original casts.
Still, I would have loved to have seen Laurette Taylor in the original GLASS MENAGERIE and Jessica Tandy in STREETCAR. My 3rd choice; to relive the opening of DOLLY! on January 16, 1964.
