Go back and listen to how the details are connected in the finale..
1. Emma Goldman's deportation (Goldman makes comments about Evelyn Nesbit..calling her a vaudeville tart and such. In the movie and novel they have even more connection.)
2. Evelyn Nesbit's fall into obscurity - She and Houdini represent show biz celebrity.
3. Houdini explains where he was when war broke out
4. Father's demise on the Lusitania is then summed up
5. Mother picks up the story explaining how her character eventually married Tateh
6. With them, and their kids they form a new family
7. and watching from a world beyond, Coalhouse and Sarah reprise their theme song "Wheels of a dream."
I like how it all dovetails together.
For those who have a problem with the "Warn the Duke" line it pops up 3 times in Act One and again in the finale. Total is less that a minute out of a 150 minute show. I would hardly consider that any kind of major structural flaw.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
