Just got an absolutely belting concert DVD. The Doobie Brothers Live at the Wolf Trap. This was filmed in 2004 and features Tom Johnson and Pat Simmons with the emphasis on their version of the Doobies (China Grove, Long Train Running, Listen to the Music, etc) as opposed to the later MIchael McDonald era. Over two hours of concert plus some very good extras too. DTS soundtrack and 16:9 widescreen format. Given the fact that it's a US concert in widescreen (unusual) and the fact that it looks so sharp, there's a good possibility that it's filmed in hi-def. A stunner of a disc. They sound as good as they ever did.
