Random note, but back when Once was first screened in Toronto, Glen stuck around after the movie/Q&A to play a little acoustic set for us. He called up a local musician from the audience named Peter Katz (though I don't remember how they met) and got Peter to sing a song for us (Glen harmonized). Then when Peter recorded his 2nd CD, he asked Glen to duet again in a more official and he agreed!
The CD's out now (iTunes worldwide, in stores in Canada) and I thought I'd spread it around. The song's called the First of the Last to Know and it's up on Peter's myspace:

Here's a short clip (with a bit of Glen's verse at the end)
