I love this thread! Theater is the one thing that comes close, sometimes more, amazing than roller coasters! 
On Broadway I've seen: Curtains, Beauty and  the Beast, The Mystery of Edwin Drood (revival cast), and Matilda (AMAZING show) 
West End: Drowsy Chaperone 
Filmed shows (not movies,but filmed on stage): Newsies, Phantom of the Opera 
And of course those cast albums that we all hold close to out hearts. Favorites include: Bandstand,Anastasia, Wicked, Dear Evan Hansen, Newsies, Matilda, Come From Away, Tuck Everlasting (a shame it closed so early), Les Misearable, Something Rotten and A Gentleman's Guide to Love and Murder  
Productions I've been in (amateur acting  ): Music Man (twice!), Bye Bye Birdie, Wizard of Oz, and Beauty and the Beast
