Olympics opening ceremony

On yesterday's opening ceremony there was at the very beginning and a bit later in the plot a kid ~10 yo with quite long hair in stone washed bibs, one strap down. Pullover mainly yellow, as street kid. I assume a girl. With 2 other kids entering a small boat with the masked phantom and torchbearer. 

I think the first scene was pre-recorded. But I think 2 later scenes were live. In the boat and later walking. And I think got the torch from Zinedine Zidan at the metro.

Sorry no pics. 

Does anybody know if these kids are taken from a known story like Phantom of the Opera. Or any details about the kids?

Update: Thanks Laurent. Yes there's a clip available. But I won't add official Olympic pics from the main show. 

I haven't found any good pics showing the bibs. The best I found is this (kid on right with a life vest over them). There's also a description of the references of the phantom. The plot is a mix and new. But it's still unclear if the group of kids have a reference of a French plot as well.
