I found this in an entry on Gadling by Jamie Rhein:

It’s from the 10th anniversary celebration of Les Misérables at Royal Albert Hall.  There were seventeen different Jean Valjeans from around the world, each of whom sang a few lines from "Do You Hear The People Sing" and "One Day More" in their native tongue.

I haven’t seen a huge number of "Broadway" shows, but of those I have Les Mis is one of my favourites.
