After weeks of releasing teaser clips online, PBS will premiere Cameron Crowe's Pearl Jam documentary, Pearl Jam Twenty, tomorrow night at 9 p.m. nationwide. And to give one last preview of what we can expect, the network has uploaded a video of the band discussing one of their frontman's more dangerous habits: stage diving. The best part about the clip isn't their comments, even if some of them are unintentionally hilarious. No, it's the fact that you get to see some great footage of Eddie Vedder flinging himself off the highest rails he can find in the building. You can watch the video below and cringe at how close dude came to getting severely injured on multiple occasions.
