Thanks for posting that great video. I recognised one of the girls so I looked at the video on Youtube and their names are in the tags.
They are Dutch girls and Yasmin Karssing, the girl with dark brown hair (tied back), appeared in the Dutch Annie (2005/2007)!
During the national tour (2005/6), she played Tessie in Albert's Angels (Eindhoven Group 1). They are still very popular and have a website (www.albertsangels.nl) and many videos on Youtube. Yasmin (whose nickname is Yassie) also has a fan site at www.freewebs.com/yassietessie where you can find lots of behind-the-scenes Annie pics under 'Fotos'. I really like her site's tagline of No More Tessie For Yassie
When Annie was extended at the Efteling Theatre (2006/7), she became Duffy in the group De Anniemals, who played the final show, which you can find on Youtube.
