That does sound like a brilliant idea!
Got the songs separated, working on track listing now.
In no particular order...
The Musical Album:
Last Of The American Girls
Last Night On Earth
Before The Lobotomy
When It's Time (Studio version from the musical soundtrack album)
Know Your Enemy
21 Guns
Christian's Inferno*
Murder City*
Mass Hysteria (Part A of American Eulogy)*
*These three songs are not actually in the musical, however, like Before The Lobotomy, they mention Billie Joe's character of Christian by name, so they get added to this album. Last of The American Girls is not about Gloria, nor does it mention her by name. In fact, of all these songs, only Mass Hysteria mentions Gloria by name, and only as a random throwaway rhyme at the end of the bridge, where he slurs her name anyway.
The Non-Musical album
Song Of The Century
21st Century Breakdown
iViva La Gloria!
East Jesus Nowhere
Peacemaker
Viva La Gloria? (Little Girl)
Restless Heart Syndrome
Horseshoes And Handgrenades
The Static Age
Song Of The Century (Reprise) [The first 30 seconds of "American Eulogy"]
Modern World [Part B of "American Eulogy"]
See The Light
I may give Restless Heart Syndrome to the musical simply because it sucks.
