Elementary school choir sings Beatles?

At least one year ago, I heard a broadcast on NPR that was about an
elementary school choir (Canadian?) that recorded popular music
(possibly exclusively Beatles tunes) in the 1970's as a pedagogical
exercise.

First, I was wondering if anyone else had heard this broadcast. What
program was it on?

Second, are those recordings available? Was the NPR article given
because these were being issued as CD's for sale?

As trite as this all might sound, the recordings were fabulous. The
NPR critic mentioned that the singing was done with such naive gusto
that, regardless of technical quality, the spirit was overwhelming. I
felt the same.

Any help would be appreciated!
