Last night of the world Les Miserables melody structure?

I believe the song is called "One Day More" and the melody structure is: Jean Valjean (solo), then Marius and Cosette (duet), then Eponine (solo) with Marius and Cosette singing underneath, then a "call and response" type thing between Enjolras and Marius, then Javert (solo), then a duet between the Thenardiers, then the entire ensemble comes in, with the various solos/duets singing underneath the ensemble.
