Listen to the interview Eli Gerstner (is that his name?)of YBC did with Nachum Segal this morning. You can listen to an archive of the show on Nachums site, also the jmintham site. You might not be so quick to condemn the 2 appearances.
If I was a parent of one of the choir boys I would not let them appear on a secular entertainment/news venue. Why purposely tempt them to spark their interest in the glitter of secular media?
