Wanna ask you something... Are all 100% of Libera's boys - christians? yes/no? Any ideas?
Maybe 90% or 50/50?
Maybe some of their parents are christians?

Somebody knows?
I think its important thing to sing and to be proud of message you sing. I hope you understand what I mean

It's not 100%, but probably still rather high. Religious expression in Britain is overall on the decline, so it would not surprise me, given what comes out of the group's publicity people, to find out that a sizable portion are not confessing, orthodox Christians. Affiliation with St Philip's (an Anglican church) is required because of Mr Prizeman's belief that the church choir idiom is the best way to create musicality in the members, but as the diocesan magazine has pointed out, members are by no means required to confess or practice Christian belief.
I understand the question, especially as I wonder the same thing about much of who I listen to. Bach was an extremely religious man, and I--as a massive consumer of his music--favor performances of his work given by artists who share in his beliefs.
As regards Libera: I would guess somewhere around 80-85%, and immediately shy away from anything more specific. Religion is an intensely personal issue--doubly so for children.
