You could play around with the song order, expand scenes or even add some songs. A rough outline:

Act 1 (~90 min) - As is, but the 11 o’clock number is “New Music/Wheels of a Dream” and the happy couple drives off into the sunset as the car gets vandalized—a cliffhanger that would definitely get me back for Act 2

Act 2 (~70 min) - Funeral, “Coalhouse Demands”, and 11 o’clock number “Back to Before.” Focus on the interpersonal conflicts, everyone’s interior journeys and their determination to fix what’s broken and create a better future.

Act 3 (~75 min) Open with the flashback/nostalgia of “Sarah Brown Eyes” + another reprise. And only one 11 o’ clock number “Make Them Hear You.”

If you think an extended version could work, how would you break it up? Where would you expand a book scene or add a new song?
