You can listen to a podcast from ABC in Australia on Why Catholics Can't Sing by pressing here. It is about a half hour show but very informative.
And of course you'll love Kumbaya sung by Benedictine Nuns in Eerie, PA on the Ed Sullivan Show wearing the traditional complete habit of the Benedictines. Sister Joan Chittiser, post Catholic, was probably a pre-Catholic somewhere in this hooded crowed. I actually saw this the night they were on. We sang Kumbaya incessantly in my home parish in Augusta, did I say incessantly?
And here they are today still singing Kumbaya!
