I came across a pretty cool website that lets you download free guitar lessons. They have about 35 lessons for free and it's actually pretty helpful if you're a beginner at guitar. Plus if you are teaching others how to play guitar, it offers a chance to see how someone else teaches it (e.g. a tough one is always trying to "explain" to someone how to strum, but he does a pretty good job at it).
The website is called iPlayMusic.com. You can also click the feed and get it as a video podcast for all you podcasters out there. I found this site through "Google Videos" while searching for some U2 concert footage ... there's actually some pretty cool close shots during last year's concerts uploaded on the site. And here's a psycho one of a girl who jumped through a basketball hoop! Crazy dude!! Enjoy!
