One of the upcoming projects for me at my parish (St. Peter Catholic Church in Stevens Point, WI) is helping teach the children's choir to sing Gregorian Chant.  To that end I've been keeping my eye open for resources to help in doing that, and success stories as well. 

Today I happened upon Fr. Rob Johansen's blog, "Thrown Back."  He had an entry about how he is teaching the school children to sing Gregorian Chant, and an MP3 of them singing Gloria VIII.

Yes, it is possible and it can be done well.  Moreover, these children who are growing up in a world where the Catholic liturgy is undergoing a restoration of the sacred, will have this Gloria under their belts whenever they worship in a "true Vatican II parish" or an international liturgy where Latin is used for the ordinary.  They will also already feel comfortable with the musical genre of chant, and be able to grow in appreciation of its beauty, and be helped to pray better when they hear it or sing it.  Great work Father Johansen!
