Gavroche always introduced himself during the reprise of "Look Down". The original London cast recording had a longer version of "Little People" that followed "Look Down", but it was cut early on in the London run, I think even before it transferred to the Palace. The full song never made it to the Broadway production, what was left of it moved to Act 2 when he busts Javert, and again when he dies. More recently, it ends after "that only goes to show what little people can do" during the Javert scene, and in the Broadway revival in 2006, his death scene was changed to a song called "Ten Little Bullets", although I believe it's been changed back to "Little People".
I actually liked his new "Look Down" lyrics in the movie, I wish it was included on the soundtrack...when they called it a 'highlights' album, they weren't kidding. Hope the full version is out soon.
Just got back from the movie...I loved it! Even Russell Crowe. No, he's not a theater-singer like we've seen on stage, but he's such a good actor that I can look past it. And that moment after the barricade falls and he sees Gavroche? Forget it...it was already sad enough.
I've seen the show 9 times, and sometimes it's a little hard to break away from what you know from the stage version, but the movie is really, really good. The live singing is amazing...that had to be the most brutal version of "I Dreamed a Dream" I ever heard. And Hugh singing the Soliloquy at the beginning was amazing.
I also loved that they incorporated so much of the book into it, especially the stuff with Eponine, and the convent. Even Marius' grandfather was there!
I need to see it again, but I was thrilled with it.
