The cowbell has infected the internets! Here are some links of interest. Check 'em out, but remember who told you about them first!
The Cowbell Project
The inspirado behind this project. It is now no longer in service. However, thanks to archive.org's Wayback Machine, we can still see the genesis of this site. I used this page as a launching pad. My eternal gratitude goes out to those at Geek Speak Weekly. They weren't perfect, though. Some of the songs on their list lack cowbell, or have what has been misconstrued as cowbell. That's OK, I fixed it up real good.
Buy a cowbell to cheer on your favorite lugers and bobsledders.
