This is Spinal Tap Redux

We've already told you about Spinal Tap reuniting for Al Gore's Live Earth concert in London on July 7. Before you start headbanging with abandon, however, check out director Rob Reiner's 15-minute sequel to that mother of all mockumentaries, This is Spinal Tap. The short was featured at the Tribeca Film Festival last month in NYC, but it's also available online at MSN's Live Earth mini site. Think of the film as an episode of "Where Are They Now?"—Nigel is breeding miniature racing horses, but has problems finding jockeys small enough to ride them; David is now a hip-hop producer who runs a colonic clinic on the side; and Derek is in rehab for Internet addiction. :: Live Earth
