I can’t believe no one has said Sunday in the Park with George (Bernadette Peters, Mandy Patinkin by Sondheim), it won the Pulitzer!
That is by far my favourite musical. It never fails to move me to tears. Even just listening to the soundtrack will bring make me cry.
I also love Hair, Sweeney Todd, [Into the Woods** (sensing a theme here? 
), Assassins and Evita (Mandy Patinkin, Patti LuPone).
I’ve never been to Broadway, but I’ve been in a bunch of musicals; I don’t think I have ever seen one that I didn’t enjoy. Ones I’ve performed in:
Guys & Dolls - young Miss Adelaide’s Mama (prologue written for me)
Carousel - Julie Jordan
HMS Pinafore - (two separate times, once as Josephine, once Buttercup)
Fiddler on the Roof - (matchmaker, can’t remember the name)
West Side Story - Maria (with a LOT of makeup & hair dye)
Little Shop of Horrors - Audrey (I)
The Music Man - a silly chorus lady
Anne of Green Gables - Anne
I’ve never seen anything ON “Broadway” so we’re talkin “regional” or “roadshow”.
WESTSIDE STORY
GREASE
FIDDLER ON THE ROOF
The recent, revised, SHOWBOAT. The music that was put back in is just stunning.
Stage musicals:
A Little Night Music
Sweeney Todd
Assassins
Passion (yes, I know, I was the one person in the world who liked it)
Lucky Stiff
Ragtime
Guys and Dolls
Chicago
Movie Musicals (that I like better than their stage counterpart):
Sound of Music
Music Man
Just got back from seeing “The Civil War” with Larry Gatlin. I should get the concept album - probably more interesting. Good show, tho…
Esprix
No, you’re not. It’s not a “favourite”, but I liked Passion. I even have a video of it somewhere
Too many to list but:
Best of the best: Phantom. No contest. Never saw Michael Crawford in it, but was completely hooked listening to the soundtrack. Have seen it three times since in Seattle, two well done productions and one simply HORRIBLE one.
Also: King and I, Passion (I, too, have the video), Into the Woods (heck, ANYTHING by Sondheim!), West Side Story, Fiddler, My Fair Lady (in the Chorus of that one), Sound of Music (Mother Abbess in high school), The Unsinkable Molly Brown (MUCH better than the movie! – chorus in high school)
and dozens of others too numerous to mention.
Fiddler on the Roof (by far the most wonderfuly compelling and honest story ever seen on Broadway, IMO)
Sweeny Todd
JC Superstar
Tommy
Into The Woods
A Funny Thing Happened on the Way to the Forum
and following in the footsteps of Fenris, if there was one show that should have been staged but never was, I’d say “The Lamb Lies Down on Broadway”, an early Genesis concept album that has great music and a very bizarre storyline.
I’ve said it before and I’ll say it again: There is nothing so obscure on this planet that some Doper hasn’t heard of it. I love the cast album for Blondel and consider it one of Tim Rice’s finest. He mentions plans for a production in Vienna in the linear notes, and I wish it had happened.
My own favorites are Phantom of the Opera, Jesus Christ Superstar, By Jeeves and Evita. Also the relatively obscure Aspects of Love and CHESS! Tim Rice’s best work.
Impressive. 
(I’d love to play Buttercup. Actually, I’d like to play Josephine, too, but I couldn’t hit the notes…)
My list of shows I’ve performed in…
The Wiz
Godspell
How to Eat Like a Child
Annie Get Your Gun
Oklahoma
The Sound of Music
The Music Man
And I’ve done crew for The Mikado, The Sorcerer, and HMS Pinafore (I was an assistant stage manager for Pinafore). Though I don’t really consider G&S “Broadway musicals” as such, or else my list would be full of G&S…
(Oh, and I was in one number from The Pirates of Penzance…and made a hundred bucks for it. Sweet. :D)

NATASHA RICHARDSON IS BRITISH!
1776 – It hasn’t been ruined by having its songs played by schmaltz musicians. And it’s based on historical incidents! How much better can it get? I saw it on Broadway during its initial run, and acted in it in college.
Fiddler on the Roof – Classic Broadway. The second Broadway show I ever saw. Probably seen as over-sentimentalized, but I still love it.
Pippin – not really based on history, but who cares? A very “show=y” show.
Godpell – so sue me. I’m an agnostic, but I loved this light version of The Gospel of St. Matthew. During the intermission, they actually served wine to the audience on-stage.
West Side Story – Bernstein’s music. The Play is structured differently than the film, so if you’ve only seen one, you haven’t seen it.
Les Miserables
Phantom of the Opera – Pepper Mill’s favorite.
Cabaret (saw it touring with Kate Shindle, who was amazing)
Chicago
Anything Goes
Oklahoma!
The Music Man
Les Miserables
My Fair Lady
Annie Get Your Gun
Kiss Me Kate
How to Succeed in Business
A Funny Thing Happened on the Way to the Forum
Imagine how it feels to be enjoying reading what fellow posters have said on a topic you enjoy, waiting to finish reading the thread so you can post yourself, and then find you’ve already posted… a year and a half ago!!!
I feel like I’ve done the time warp… again!
I’ve really enjoyed:
**Kiss Me Kate
Phantom of the Opera
The Fantasticks **I know off broadway
How to Succeed with Matthew Broderick

I’d LOVE to include some Gilbert & Sullivan myself, but the only G & S show I know was on Broadway is “Pirates of Penzance,” not one of my favorites. If we must stick to Broadway, my favorites are:
#1- Fiddler on the Roof
#2- Les Miserables
#3- Guys and Dolls
#4 Show Boat
#5- Cabaret
#6- A Chorus Line
#7- My Fair Lady
#8- Chicago
#9- Joseph & the Amazing Technicolor Dreamcoat (the only Webber musical I really like as a whole)
#10- South Pacific (dated story, but still R & H’s best collection of songs)
The Fantastiks
A Chorus Line
West Side Story
hmmm… oh yeah! RENT RENT RENT RENT RENT!!!
and maybe , the revival of " You’re a good man , Charlie Brown"
but only because the guy in that was from RENT RENT RENT RENT RENT RENT RENT RENT RENT RENT
TITANIC (the GOOD Titanic story from 1997)
CHESS
THE FANTASTICKS
ON THE T0WN
WEST SIDE STORY
