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.

THE SWORD IN THE STONE is just about the best fantasy that I have ever read. It is a story of the childhood of Wart, later known as King Arthur, and is filled with delightful adventures that fulfill childhood dreams-such as becoming a owl and being able to fly. Not only that,but this book is also filled with the wonder and the wisdom of T.H.White. To read it is an undescribable experience.I recommend it uncondoitionally to all lovers of fantasy
