The 25 singers in The Blue Ribbon Glee Club are Chicago’s (first?, only?) finest punk rock choir. You can download their versions of “Where Is My Mind?” by Pixies, “Waiting Room” by Fugazi, “Whole Wide World” by Wreckless Eric, and “Spanish Bombs” by The Clash, on their website. There is also a video of them singing “Where Is My Mind” (youtube).
If you are interested in joining a similar project, some punks in Colorado Springs are looking for members to join their Anarchists Marching Band. Sounds like a blast to me.
