Phil Collins singing "Take Me Home" and Mark Knopfler performing "Brothers in Arms" and "Money for Nothing" are fantastic; heck, Elton, McCartney, Sting, Eric Clapton, Sting, Jimmy Buffett, Carl Perkins and Arrow are all great. This is a wonderful concert; I just wish I could have heard it in person.This DVD looks fantastic and sounds terrific--especially on a DTS capable system like mind. I buy music DVD's only if I can see that they have DTS encoding on the disk (Amazon please take note). However, in a few places--just a couple--the sound quality of "Music for Monserrat" falls down a wee bit compared to other music DVD's I have; otherwise, I would have rated it 5 stars.That said, this is a great DVD for those like me who love these artists.

I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO.
