One of Rock Daily's favorite rock films, the heavy metal mockumentary This Is Spinal Tap, finally hits stores today as a stunning Blu-ray DVD, 25 years after the band first turned the amp up to 11. To celebrate seeing David St. Hubbins, Derek Smalls and Nigel Tufnel in all their high-definition glory, Rock Daily has this exclusive bonus clip from the DVD, featuring the band performing "Stonehenge" during their reunion gig at the 2007 Live Earth concert in London's Wembley Stadium. The DVD also features a conversation with Tufnel as he discusses the mystery of Stonehenge. If by some chance you have managed to somehow avoid seeing This Is Spinal Tap, we recommend you run out now and go watch it. For those readers who share our love of the film (you guys did vote them Best Fictional Band in a past Rock List), leave your favorite scenes and best lines from the film in the comment section.
