That's awesome The choir I was in when I was at school did it too (around 2005). When the teacher announced the song I hadn't heard of it, but by the time we were performing it during assembly, I struggled to not sing it the way Billie Joe does, instead of the harmonies we'd be taught
I have one that I bought at Wembley Stadium in 2010 - I can't remember what's in it because I haven't looked at it in years but I actually remember being annoyed they didn't choose better photos!
