21. The Return to Boston (5:26)
22. The Dying Alien Appears (0:40)
23. The Reunion (3:39)
24. Epilogue (3:29)

Basically, the thing would go like this, with the music available in the cd:
1. Prologue
2. After the Storm
3. The Intersection Scene
4. Ashes
5. Escape From the City
6. The Crash Site
7. Floating Corpses
8. Refugees
9. The Ferry Scene
10. Reaching the Country
11. Probing the Basement
12. The Confrontation with Ogilvy
13. Escape from the Basket
14. The Return to London
15. The Reunion
16. Epilogue

Tracks like After the Storm and Ashes are in the "Escape from the Basket" track, and Floating Corpses in "The Confrontation with Ogilvy". I guess you won't have any difficulties in editing it.

Hope I helped,
