NOTP Countdown:

Sarahdenrara at R2R forum informs us, that there is also a blog in French/Dutch from one of the singers of the choir called Maurice (it is his nickname):

He writes today that he thinks Per is really into it and happy to be there, Marie too even if she seems a bit fragile. He adds that you have to keep in mind that artists never give a 100% during rehearsals.
